Hogle Zoo

Completed in 1971, the Small Animal Building is the zoo's oldest exhibit. It is one of the few exhibits left in North American zoos that are dedicated to small mammals, reptiles, amphibians, and birds. Current examples include the National Zoo's Small Mammal House and San Diego Zoo's Reptile House. While many of these exhibits divide animals based on taxa, Hogle Zoo's exhibit follows the more modern 19th century idea of displaying animals based on the species' biomes. The Small Animal Building includes four zones, each dedicated to a specific habitat. These include the Tropics Zone, Temperate Zone, Desert Zone, and Rainforest Atrium. Surrounding the Small Animal Building are outdoor habitats for reptiles during Utah's warmer months and an exhibit for red foxes.

While the exhibit encompasses an innovative theme for exhibiting animals, the habitats themselves are dated. The Small Animal Building is the oldest building on the zoo's campus. Despite being functional and up to code, the zoo is looking to renovate the facility in the zoo's master plan.

Temperate zones are found across the globe in the Americas, Europe, Africa, Asia, and Australia. These areas have a wider range of temperatures and often experience distinct seasons as compared to tropical zones. Most humans live in temperate zones resulting in large urban developments of these areas. Biomes found in temperate zones include temperate deciduous forest, temperate coniferous forest, temperate broadleaf and mixed forest, temperate grasslands, savannas, and shrublands, flooded grasslands and savannas, montane grasslands and shrublands, Mediterranean forests, woodlands, and scrub, and mangroves.

The Temperate Zone in the Small Animal Building features animals from habitats. Some of the reptiles found in the exhibit include Rhinoceros iguana, Puerto Rican boa, and flat-backed spider tortoise. The exhibit is also home to a pair of Siamese crocodiles. This critically endangered species is incredibly rare in captivity and can only be found at five other accredited facilities within the Association of Zoos and Aquariums.

Mammals in the Temperate Zone include rock hyraxes and black-footed cats.

The Desert Zone, features animals found in Deserts and xeric shrubland biomes. This is the largest terrestrial biome covering nineteen percent of the Earth's landmass. These habitats experience extreme temperate changes from high temperatures during the day to cold at night. The fauna that live in these regions have evolved adaptations that ensure their survival.

The Small Animal Building's Desert Zone is anchored by an open air aviary that resembles the Sonoran Desert featuring white-winged dove, northern cardinal, and desert tortoises. The Desert Zone also features reptile species including Kenyan sand boa, pancake tortoise, and Gila monster. Amphibian species include Colorado River toad and Kaiser's mountain newt. Utah native species featured in the exhibit include yellow-bellied marmot, turkey vulture, and common chuckwalla.

The mammal species found in the exhibit highlight specific adaptations for desert life. Sand cats have large ears which allow heat to easily leave their bodies, and nine banded armadillos use their claws to easily dig into sand to find food.

The tropics include biomes that span around the Earth's equator. These areas receive the most sunlight and experience extreme rainfall. Habitats in this zone include tropical rainforests and monsoon forests.

The Tropics Zone features mammal species from the Amazon River Basin including white-eared titi monkey, Linne's two-toed sloth, and kinkajou. The exhibit also includes reptile species found on the islands of Oceania including green tree python, emerald tree monitor, and the prehensile-tailed skink.

The Rainforest Atrium is a free-flight aviary featuring a variety of birds from around the world. The exhibit features natural light cycles through a glass dome that covers the exhibit. Artificial rock work, a waterfall, and live plants create a naturalistic habitat. Free-flight bird species in the Rainforest Atrium include speckled mousebird, superb starling, spur-winged lapwing, roseate spoonbill, pied imperial pigeon, rose-ringed parakeet, helmeted guineafowl, red junglefowl, and the critically endangered Edward's pheasant. The Rainforest Atrium is also the winter home for the zoo's Aldabra tortoises, radiated tortoises, and leopard tortoise.

The Great Apes exhibit opened in 1983. The exhibit, which cost $1,040,000, includes four indoor habitats for the apes during Utah's cold winter months as well as two outdoor yards. The exhibit currently features a breeding troop of western lowland gorillas and two groups of Bornean orangutans. The exhibit used to be home to a trio of chimpanzees.

Husani was brought to Hogle Zoo in 2010 to form a bachelor troop with Tino, another male who lost his longtime mate Muke the year prior to cancer.[9] Husani was born at the Bronx Zoo in 1991 and came to Utah from the Birmingham Zoo. A year after Husain's arrival, the zoo also welcomed two females, Jo Ray K and her daughter Jabari from the Denver Zoo. They were brought to Hogle Zoo to start at family troop with Husani upon Tino's death. The zoo successfully housed the four gorillas in two troops until Tino's death in 2015.[10] It was at that point when introductions began between Husani and the girls.

The Species Survival Plan closely monitors breeding among gorillas in accredited zoos. Breeding recommendations are not made until several factors are assessed by a specialist including exhibit factors, and troop behavior. Before a breeding recommendation was approved, Jo Ray K and Jabari were both put on birth control while they lived with Husani. After an assessment in 2019, Husani and Jabari were approved for a breeding recommendation. On July 6, 2020, Jabali gave birth to her daughter Georgia, the first birth for this pair and only the second gorilla born in the zoo's history.

In early 2022, Jo Ray K, the troop's matriarch died.[11] Prior to her death, the SSP had already made a recommendation to transfer two more females to add to the zoo's troop. Later that summer, Mary and her daughter Pele moved to Utah from Busch Gardens Tampa Bay to join Husani, Jabari, and Georgia.[12] Introductions began that summer and all five gorillas currently live together.

Adjacent to the gorillas, are habitats for Bornean orangutans. The zoo is home to a breeding pair male Mia and female Kawan as well as orphaned siblings Acara and Tuah.

Acara in the zoo's Great Apes exhibit in 2006

Acara was born on Mother's Day in 2005. Acara was larger than most orangutans at birth. Her mother, Eve, was in labor far longer than the four to five hours normal for an orangutan birth. Therefore, specialists from the University of Utah Hospital were brought in to perform a C-section. Acara was delivered after a two hour operation but was not breathing properly. She was taken to the University Hospital where she spent the night in an incubator. When Acara was taken back to the zoo and given back to her mom, Eve did not recognize her baby. Acara had to be hand-reared while introductions with her mother slowly took place.[13] It took 20 staff members and 12 volunteers to raise Acara 24/7 for over nine months until she was put back with Eve full time.[14]

Elija, affectionately known as Eli, came to Hogle Zoo in 2004 as a mate for Eve, a recommendation made by the Species Survival Plan. Eli was the father of Acara, but had not role in raising her as is typical with wild orangutans. Eli had become a social media star for accurately picking the winner of the Super Bowl for seven consecutive wins. His accomplishments garnered him recognition in Sports Illustrated magazine and on MSNBC. In 2011, Eli was diagnosed with breast cancer, a condition rarely seen in apes. He was only the third orangutan to be diagnosed with the cancer and the first male. A surgeon from Utah's Huntsman Cancer Institute performed one of two operations that removed the original mass. Despite veterinarian staff monitoring his condition closely, Eli ultimately lost his fight to breast cancer on September 6, 2014.[15]

Acara and her mother Eve in 2006

Eve was pregnant when her mate died. She gave birth to Tuah, a male, on November 4, 2014. Again Eve had complications at birth and needed a C-section. Like his sister, Tuah needed to be hand-raised. While Eve responded well to the surgery initially, her behavior quickly changed. Three and a half weeks later Eve had died. A necropsy found that Eve's death was not related to the childbirth, however, no cause of death was found. The necropsy did find several medical problems that were unaware of by zoo staff.[16]

Tuah while being hand-raised in 2014

While Tuah was being hand-raised, keepers began training his older sister Acara to be his surrogate mother. While other adult female orangutans had successfully been surrogates to orphaned babies, an older sibling had never been recorded as being one. Through positive reinforcement, keepers trained Acara to hold a baby using a stuffed animal. Acara was still young and full of energy so it was important she learned how to be gentle. Tuah was introduced to his big sister when he was three months old. In March 2015, the two started living together full time. Tuah made his public debut on April 11, 2015 to the 9,000 guests in attendance who wore "I met Tuah" pins.[17]

Acara and Tuah have lived together at Hogle Zoo ever since. Acara has proven as a successful surrogate in this first ever scenario. In fall of 2016, the siblings were introduced to adult male Mia who came to Hogle Zoo from the Greenville Zoo in South Carolina as a potential future mate for Acara when she is ultimately separated from Tuah.[18] On June 8, 2021, the zoo received Kawan, a female from the Henry Vilas Zoo in Wisconsin. Her move was recommended by the Species Survival Plan as a mate for Mia.[19] Currently the zoo holds Mia and Kawan separate from Acara and Tuah.

The A. LaMar Farnsworth Primate Forest opened to the public in June 1997. The exhibit was named after the former zoo director A. LaMar Farnsworth, who served as director for 33 out of his 45 years at the zoo. The exhibit, which cost $400,000 to construct, replaced the old concrete Monkey Island exhibit. Primate Forest offers lush, naturalistic landscapes for several species of primates including black howler monkey, eastern black-and-white colobus monkey, Colombian spider monkey and Nicaraguan spider monkey. The exhibits were specifically designed for each species. The large central exhibit for the colobus monkeys, which is 5,100 square feet and reaches a central height of 18 feet, offers trees where the primates can jump from. Each exhibit also has water features.

The push for a new elephant habitat was issued by the Association of Zoos and Aquariums' new 2001 guidelines for elephant care. While many AZA zoos opted to relocate their elephants, Hogle Zoo already had plans for a new facility. In 2003, Salt Lake County voters approved Proposition #1, a bond that allotted Hogle Zoo $10.2 million to redo the zoo's elephant and feline exhibits. The following year, construction began on the $5.5 million Elephant Encounter, an exhibit that would increase the elephant's habitat by 400 percent.[20] The exhibit opened in June 2005, completing the zoo's largest major animal exhibit in 25 years. The new home featured three female African bush elephants Hi-Dari, Christie, and Misha, as well as southern white rhinoceros half-siblings Princess and George. The exhibit received great praise even from the president of AZA at the time, Bill Foster, noting, "Hogle Zoo is leading. They are ahead of the curve. (Hogle) Zoo will be known globally for the advancement that it's making now."[21]

Elephant Encounter features two natural outdoor exhibits. The first habitat is a large Serengeti inspired yard with a swimming channel that spans 10.5 feet deep and holds over 110,000 gallons of water. A second "working yard" allows guests to see how zookeepers train and care for the large mammals. This habitat also features overhead heaters and heated concrete floors to ensure the elephants are comfortable in winter months. Guests view this habitat from the African Lodge, a 2,600 square foot open-air African structure, constructed of wood and thatch materials. The Convergys Corporation pledged $200,000 to become the title sponsor of the structure. A kopje replica allows guests to come face-to-face with the zoo's rhinos in a third habitat.

Christie with her daughter Zuri in 2009

Starting in 2006, attempts were made by a team of German veterinary scientists from the Leibniz Institute for Zoo and Wildlife Research in Berlin to artificially inseminate female elephant Christie. The team used samples from a male elephant named Jackson at the Pittsburgh Zoo. On the third attempt, Christie became pregnant. After a 22-month-long gestation, Christie gave birth to a healthy 251-pound female calf on August 10, 2009. The calf was named Zuri meaning "beautiful" in the Swahili language.

In 2020, the animal activist group In Defense of Animals added Hogle Zoo onto their list of 10 Worst Zoos for Elephants.[22] The group called upon Utah's harsh winter climate and the zoo's unnatural herd dynamics. With the passings of Misha in 2008 and Hi-Dari in 2015, the zoo's herd is down to just Christie and her daughter Zuri. Current AZA regulations mandate that herd sizes should be no less than three. A Hogle Zoo spokesperson assured that the zoo is "working closely" with the AZA and Species Survival Plan "to increase the size of our herd, but that takes time. Our current master plan calls for a greater investment in elephants, with bigger barn, additional yards, and large walking paths. We are committed to the species."[23]

In May 2023, Hogle Zoo officials announced a pause to their elephant program. After caring for elephants for over 100 years, the Hogle Zoo decided that the best plan for their current elephants, Christie and Zuri, would be to relocate them in the fall of 2023 to another accredited facility. The plan came after a comprehensive evaluation that was animal-driven giving the elephants the opportunity to live in a more behaviorally natural environment and have the chance to breed.

The zoo's Chief Executive Officer Doug Lund was quoted as saying,

"Utah's Hogle Zoo is progressing through an exciting and transformational planning process to help ensure we meet the changing needs of our community and the complex needs of animals in the Zoo's care. We have talked to many professionals, consultants, community members, and our staff as we carefully assessed what is best for all our animals, including elephants Christie and Zuri. The ultimate choice to move Christie and Zuri is to provide them both the best chance to have a calf in the important social dynamic of a multigenerational herd."[24]

The zoo noted that the possible return of elephants will be evaluated in a new master plan which is currently being developed. The zoo has yet to announce which facility the elephants will be sent to or what will be housed in Elephant Encounter once the animals leave.

Asian Highlands logo from the exhibit's opening in 2006

Just months after the opening of Elephant Encounter in 2006, construction began on Asian Highlands, the second project funded by the 2003 $10.2 million bond. The exhibit sought to convert the dated indoor Feline Complex's barred concrete cages into lush outdoor habitats for cats from the colder regions of central Asia. The zoo's existing female Amur tiger and snow leopard would enjoy the new habitats as well as new additions to the zoo including a male Amur leopard, a male Amur tiger, a male snow leopard, a trio of Siberian lynx brothers, and eventually Pallas cats. The exhibit opened on June 29, 2006.[25]

Asian Highlands resembles a village in the Himalayas with five lush hillside exhibits of which the cats rotate between through a system of chutes. A large catwalk connects from the holding areas (the renovated existing Feline Complex) to the main habitat allowing the cats, usually reserved for tigers, to walk over guests. The central plaza, themed with prayer flags, includes Cat Wok Cafe and Grandma's House, an indoor interpretive area with a window into one of the habitats. Realistic rock work, plantings, and water features along with the geographic theming proved to be the exact upgrades the area needed.

In May 2015, four male Turkmenian markhor from the Bronx Zoo took up residence in the rocky habitats above Asian Highlands that once held bighorn sheep and stone sheep adding to the exhibit's diversity of mountain dwelling Asian species. Two Chinese goral would later join them but have since left the zoo's collection.

The success of Hogle Zoo's Asian Highlands solidified the facility as a zoo on the come up. The theming of the exhibit influenced other exhibits including San Diego Zoo's Asian Leopards exhibit in 2015, Denver Zoo's the EDGE in 2017, and Omaha's Henry Doorly Zoo and Aquarium's Asian Highlands in 2019.

Hogle Zoo's success in its participation of Species Survival Plans is most noted in its prolific breeding at Asian Highlands. The first babies of Asian Highlands were born in 2009.

Tiger cubs Bronevik, Vikenti, and Kiril born on June 2, 2009

Three male Amur tiger cubs were born on June 2, 2009, to mother Basha and father Kazek.[26] Bronevik, Kiril, and Vikenti, as they were named, have since moved to other accredited facilities to participate in the program themselves. Kiril travelled the farthest, moving to Japan as part of the Global Species Management Program.

The zoo's former snow leopard mated pair, Nema and Himesh produced two offspring. Nema first gave birth to male cub Himal on May 7, 2009. She had another male cub on April 16, 2012. Chimeegui still resides in Asian Highlands, where he is recommended to breed with female Babs.

Two litters of Pallas cats have been born to parents Haru and Patenka in 2017 and 2018. The pair have produced a total of nine kittens.

Possibly Hogle Zoo's most significant contribution to the Species Survival Plan is their breeding success with Amur leopards. The species is commonly considered the most endangered big cat in the world. Around 300 individuals are left in their native habitat of Far East Russia and northeast China. Around 200 exist in zoos globally. To help boost the gene pool of the American captive population, female Zeya was brought to Hogle Zoo in 2016 from a facility in Kent, England, to breed with the zoo's resident male Dmitri. Since 2017, the Amur leopard pair have produced four litters and a total of seven cubs, most recently Jordan and Chelsea on December 25, 2021.

These SSP programs are important for creating a surplus for these species who are at the brink of extinction.

To the delight of Utah's public, red pandas returned to Hogle Zoo on May 2, 2018, with the opening of the Janet Quinney Lawson Red Panda Exhibit. The species was absent from the park when construction began on Rocky Shores in 2010. A new exhibit for the charismatic creatures was constructed at the entrance of Asian Highlands. This was the first of two exhibits constructed under the directorship of Steve Burns.

Red Panda exhibit is added to Asian Highlands in 2018

On June 23, 2023, after an approximate 132-day pregnancy, the zoo's female red panda Priya gave birth to a cub. Priya arrived at Hogle Zoo in June 2022 on a breeding recommendation. She was paired with the zoo's resident male Mow Mow. This was the first red panda birth in the zoo's history.[27]

Rocky Shores logo from the exhibit's opening in 2012.

In 2007, Hogle Zoo officials announced plans to construct an Arctic themed exhibit as part of their newly unveiled master plan. The exhibit would replace the dated Bear Grotto from the 1950's and see the return of polar bears to Utah. The proposed exhibit planned to also see the return of snowy owls and seals as well as new species including arctic fox. This plan eventually evolved into Rocky Shores, an exhibit showcasing the physical, cultural, and social landscape of the western shores of North America.

Funding for what would be the zoo's largest and most expensive exhibit was secured through a 2008 Salt Lake County bond of $33 million as well as a $3 million grant from the George S. and Dolores Doré Eccles Foundation.[28][29] Construction for Rocky Shores began in 2010, transforming a three-acre site at the northwest end of the zoo. [30] After a two-year construction period, the $18 million Rocky Shores exhibit opened in a ribbon cutting ceremony with Salt Lake City Mayor Ralph Becker on June 1, 2012.[31]

Rocky Shores features wildlife from Pacific Northwest stretching from Oregon to Alaska. From the R. Harold Burton Otter Falls habitat, guests can view bald eagles and North American river otters. The George S. and Dolores Doré Eccles Tidewater Cove provides underwater views of California sea lions, harbor seals, and polar bears. A salmon cannery inspired tower overlooks Bear Meadows which is home to the zoo's grizzly bears. Underneath Rocky Shores are dozens of pumps that help filter the exhibit's 350,000 gallons of water.[32]

On May 1, 2012, Rizzo, a female polar bear from the Cincinnati Zoo, arrived in anticipation of the Rocky Shores' opening. Rizzo was the first polar bear to be seen in Utah since 2003. Rizzo delighted guests and was famous for swimming up to the glass and back diving into her habitat's pool. After a week of end-of-life care, zoo officials made the decision to euthanize Rizzo on April 9, 2017. The nineteen-year-old female had been suffering from renal failure.[33]

On September 16, 2017, the zoo received Nora, a female from the Oregon Zoo in need of relocation. Nora achieved global fame after her mother Aurora abandoned her days after her birth on November 6, 2015, at the Columbus Zoo. In an effort to keep Nora alive, she was hand raised by her keepers and quickly grew popularity on social media as people from around the world watched Nora grow up. Nora was sent to the Oregon Zoo in 2016 in hopes that she would learn natural bear behaviors from the zoo's older female Tasul.[34] When Tasul died that November, Nora was again left alone, and the Oregon Zoo saw an opportunity to relocate Nora while they created an improved polar bear exhibit. Thus, Nora was sent to Hogle Zoo where she could be introduced to a female of a similar age.

Hope, born a month after Nora at the Toledo Zoo, arrived at Hogle Zoo on September 20, 2017. Introductions between the young bears began shortly after their arrival, and the two became fast friends. They would often be seen rambunctiously playing in their home at Rocky Shores. Their antics got Nora into a bit of trouble when she broke her front leg in February of 2019. A team consisting of specialists from Texas A&M, North Carolina State University, and the University of Utah performed surgery on Nora on February 4, 2019. Nora made a full recovery with the help of heavy-duty orthopedic hardware in her leg.[35] By 2021, it was time for the two girls to embark on a new chapter of their lives. On January 29, 2021, Hope moved to the Brookfield Zoo on a breeding recommendation with the zoo's resident male Hudson. Nora's new habitat at the Oregon Zoo, Polar Passage, was ready for her. She arrived back in Portland on March 9, 2021, where she currently resides with her friend Amelia Gray.

On February 26, 2021, Nikita, a fourteen-year-old male polar bear, took up residence at Hogle Zoo. Standing at 10½ feet-tall, Nikita was the first male polar bear to call Rocky Shores home. Arriving from the North Carolina Zoo, Nikita's move to Utah was coordinated by the Polar Bear Species Survival Plan.[36] His mate, Neva, a five-year-old from the Maryland Zoo, arrived on November 16, 2021.[37] The two have been introduced to each other, and zoo officials are hopeful the pair will produce offspring continuing Hogle Zoo's long history with polar bear breeding.

Many of the animals that live in Rocky Shores were rescued from the wild and have now found permanent homes in Utah. In July 2010, three grizzly bear cubs were left orphaned after their mother killed a man and injured two others outside of Yellowstone National Park and needed to be euthanized. The cubs were too young to survive on their own in the wild, so it was determined that they would live out the rest of their lives in captivity. The cubs, two females named Dolly and Lou Lou and a male named Koda, were first sent to Zoo Montana, then New York's Buffalo Zoo, before finding a forever home at Rocky Shores in 2012. [38] Most, if not all, grizzly bears in AZA accredited facilities are rescues. They are not bred to ensure space for more rescues. Koda, Dolly, and Lou Lou play an important role at Hogle Zoo educating guests on how to safely interact with wildlife to ensure an event like theirs doesn't happen.

One of Hogle Zoo's male California sea lions, Maverick, is also a rescue. He was found abandoned on a beach in California at less than a year old. Maverick was rehabilitated at the Fort MacArthur Marine Mammal Center in San Pedro, California. Because of his young age and his sustained injuries, Maverick was not eligible for release back into the wild. Hogle Zoo has provided a permanent home for Maverick since his arrival on May 5, 2012.

Female bald eagle Marie and male Nemo were both found injured in Alaska. They were taken in by the Alaska Raptor Center in Sitka. Their injuries required slight amputations to their wings. Unable to fly, the pair had no chance of survival in the wild.[39] Nemo arrived at Hogle Zoo in spring of 2016 where Marie would join him a couple of years later.

Rocky Shores has become a haven for rescued animals, giving them a place where they can lead natural lives and receive the specialized care they need. Since the exhibit's opening in 2012, Rocky Shores has been home to ten rescued animals.

Art for the opening of the African Savanna in 2014 featuring the exhibit's animals

In the fall of 2012, Hogle Zoo broke ground on an expansive 4.5 acre complex that would showcase animals from east Africa's grasslands. The project transformed the heart of the zoo which previously was home to the zoo's Discoveryland. The exhibit became the zoo's first mixed-species habitat showcasing several species together as they would be in the wild. Plans for the complex first started in 1999 under the directorship of Craig Dinsmore when he proposed an $80 million-plus renovation of the 42 acre zoo.[40] Despite public support for an African Savanna habitat which would greatly increase the animal welfare of its animals, the zoo struggled to finance the exhibit. In 2007, Hogle Zoo lost a bid for $65 million in taxpayer money.[41] The following year, the zoo was funded $33 million through a Salt Lake County general-obligation bond. This helped fund a new animal hospital (2009), the zoo's Rocky Shores exhibit (2012), and finally the $16 million African Savanna.

African Savanna logo from the exhibit's opening in 2014

The exhibit was completed in two phases beginning with Lion Hill which had a soft opening in May 2014. The exhibit officially debuted with the completion of the Grasslands on June 2, 2014.[42] The exhibit is anchored by Twigga Terrace, a fifty-foot in diameter platform that looks out onto the habitat. Daily giraffe feeds are offered on the terrace during summer months where guests can come face-to-face with the tallest land animal. On June 6, 2019, the zoo debuted the James E. Hogle Jr. Meerkat Manor which added meerkats and crested porcupines to the African Savanna. All habitats in the African Savanna are outlined by amazing views of the Rocky Mountains that surround the landscape.

Before the opening of Lion Hill, African lions had been absent from Hogle Zoo for a decade. The zoo's former lions were housed in the Feline Building, a series of grottos and barred cages reminiscent of typical 1800s zoo designs. However, when lions returned to Hogle Zoo, their habitat was state-of-the-art.

Lion Hill features two grottos with freshwater and a grassy hill topped with a large rock for the lions to bask in. Large class walls allow guests to come nose-to-nose with the large big cats. Heated rock work allows the lions to be comfortable outside during Utah's cold winters. The naturalistic exhibit overlooks the adjacent Grasslands habitat, giving the lions ample enrichment opportunities. The habitat also features a training wall, allowing guests to view daily training demonstrations between keepers and the lions.

Lion cubs Brutus, Titus, and Calliope born on January 24, 2016

Lion Hill debuted with four residents: Vulcan and Baron, brothers from the Montgomery Zoo, and sisters Seyla and Nobu from the Woodland Park Zoo.[43] The four lions were slowly introduced to form what is now Hogle Zoo's current pride. These lions were brought together upon a recommendation by the African Lion Species Survival Plan, a program that works to ensure genetic diversity among North America's lion population within the Association of Zoos and Aquariums. In 2016, the pride became bigger when Nobu gave birth to males Brutus, Titus, and female Calliope on February 24. This litter was only the third time lion cubs had been born in the zoo's history. On May 16, 2016, the cubs made their public debut with their mother alongside their father Baron and fellow pride members Vulcan and Seyla.[44] Brutus and Titus were moved to the Brookfield Zoo on March 17, 2020, as it is typical for male cubs to leave the pride after two years.

The Grasslands makes up the major footprint of the African Savanna consisting of three yards for hoof stock, and buildings for the animal's overnight housing. When the exhibit opened in 2014, a diversity of birds and ungulates from and eastern and southern Africa roamed together in the habitat. These species included giraffe, Hartmann's mountain zebra, lowland nyala, common ostrich, Egyptian goose, and helmeted guineafowl.

Three two-year-old male lowland nyala arrived at Hogle Zoo in April 2014 prior to the exhibit's opening. Unfortunately, one of them died less than a month after its arrival on May 13, 2014, possibly due to stress. The other two struggled to acclimate to the exhibit. This may possibly be due to the skittish and timid nature of the species. Hoping that adding another male would help the others feel comfortable, another nyala arrived in September 2014. However, the nyala never acclimated and in September 2015 the three males were sent to other zoos. The zoo's two elderly Egyptian geese died not too long after the exhibit's opening. The zoo has never replaced these two species. Common warthogs were added to the Grasslands habitat with the addition of Meerkat Manor in 2019.

The zoo's giraffe herd was moved from their former giraffe yards at the west end of the zoo to the more spacious and naturalistic Grasslands habitat. In the winter, they enjoy a heated paddock near the train station. This allows guests to still view the African-dwelling species during the colder months. Since the opening of the African Savanna, three female giraffe calves have been born including most recently Reyna who was born on September 24, 2022. The zoo's current herd includes females Stephanie, Minka, Reyna, and male Ja-Raffe.

Hogle Zoo has seen great success with its herd of Hartmann's mountain zebra. The species is found in the mountainous steppe region of southwestern Africa. The herd has acclimated well to Utah's climate and can often been seen running through the snow during the winter. Since the exhibit's opening, a total of seven calves have been born at the zoo through the Hartmann's Mountain Zebra Species Survival Plan. These births are significant as the species is listed as vulnerable by the IUCN.

Night quarters for the Grassland's guinea fowl and warthogs reside underneath Twigga Terrace.

This exhibit was added to the east end of the Grasslands habitat in 2019. It just so happened that the additions of meerkats and warthogs to the savanna coincided with Disney's 2019 remake of The Lion King. The exhibit was sponsored by and named after James E. Hogle Jr., a member of the zoo's board of directors for over forty years and part of the family who donated the land of which the zoo still stands on. Sadly, Hogle Jr. died in October 2020. Meerkats were his favorite animals saying at the opening of the exhibit, "They're terrific. They are like little people, they have their own little colonies and families, they are just fun to be around."[45]

Meerkat Manor provided new outdoor and indoor spaces equipped with termite mounds for the zoo's meerkats who moved from the Small Animal Building. They share their space with two crested porcupines.

The Aline W. Skaggs Wild Utah exhibit will be the newest major development since 2014's African Savanna. The exhibit will transform three acres of the zoo's east side which was previously only visible by the train. Featured in the exhibit will be Utah native species with the intent to educate Utah's public and tourists about the state's iconic wildlife. Making a triumphant return to the zoo will be species like mountain lion, desert bighorn sheep, and wild burro. The exhibit will also provide new expansive habitats for the zoo's current native animals including a rescued bobcat named Loki, North American porcupine Barton, as well as desert tortoises, burrowing owls, and common chuckwallas. Other new animals that will be making their debut in the exhibit are gray foxes and raccoons that will rotate between three exhibits with the bobcat and North American porcupine. These exhibits are connected by a chute that goes over the guest pathway.

The guest pathway of the new exhibit will include a boardwalk around Emigration Creek, a historic Utah waterway which runs through the zoo's campus. A nature trail will lead down to the water where guests will experience and learn about Utah's riparian habitats. Other features of the exhibit include an education "campground" as well as a pollinator garden which will attract native pollinators and bees. Hands on experiences will include a burrow brushing station, Education Maker Space, and an overlook tower.[46]

The Wild Utah exhibit is expected to cost $22 million, triple the cost of the initial construction bid. $7.5 million came from Zoo Operations, $5 million from private donations, and $1.5 million from state funding.[47]

Construction began in late 2022, with an expected opening sometime in 2024.

The expanse of the new Wild Utah exhibit provides an opportunity for a brand-new facility for the zoo's animal ambassadors. Original plans for this project started a couple of years prior for a new animal ambassador building on the zoo's South Rim. However, the COVID-19 Pandemic haltered this plan. Now the building, which will house over 100 animals, is back on track for the Wild Utah exhibit. This new facility will focus on smaller Utah native species including northern flying squirrel, yellow-bellied marmot, Pituophis catenifer deserticola, Lampropeltis pyromelana, as well as the aforementioned burrowing owl, desert tortoise, and common chuckwalla.

The facility will also feature the Utah Amphibian Conservation Room which will become the new home of the zoo's Boreal Toad Conservation Center. This project works to works to protect boreal toads, a subspecies of western toad, whose population has declined in the past 20 years due to habitat loss and fungal disease chytrid. The center is currently home to 20 toads that were collected from Utah's Paunsaugunt Plateau. Theses toads have been carefully bred so that their disease-free offspring can be released back into the isolated population.[48]

The Education Animal Center will support Hogle Zoo's iSEE program which brings animal ambassadors to second grade children across Utah helping to educate 50,000 students yearly about their native Utah wildlife.

The Zoofari Express crosses over the bridge that will now be used as a guest walkway for the upcoming Wild Utah exhibit.

Hogle Zoo's famous train ride closed on September 26, 2022, in preparation for construction of a new and larger track which surrounds the Wild Utah exhibit. From the train guests will be able to see bighorn sheep, mountain lion, and wild burro, as well as the zoo's African Savanna species. Incorporated into the track is the existing Moffat Tunnel, a guest favorite.

Before the attraction's closure in 2022, the Zoofari Express was in service for about 53 years and provided rides to between 12 and 15 million guests.[49]

Other than supporting Hogle Zoo's iSEE program and Boreal Toad Conservation Center, the Wild Utah exhibit will allow the zoo to participate in several other conservation programs. The exhibit will provide space for orphaned mountain lions and bobcats who have been deemed un-releasable due to their young age at rescue. The exhibit will also allow the zoo to participate in the Desert Bighorn Sheep Species Survival Plan, a nationwide effort to increase the genetic diversity of the threatened species. The exhibit's wild burros will be a population of animals that were collected by the Utah Department of Natural Resources. These feral animals can cause problems in native ecosystems by spreading diseases and destroying native plants.

Oasis Plaza serves as a connecting hub in the center of the zoo. Four paths stemming from the plaza lead guests to all corners of the zoo. The zoo's Conservation Carousel beautifully decorates the plaza and is a popular attraction. The plaza's Oasis Cafe serves pizza, sandwiches, ice cream, and drinks.

The World of Wildlife Amphitheater is accessible from the plaza. The amphitheater which was once home to the popular World of Flight show,[50] is now home to the zoo's Canine Champions for Conservation program.

Completed in 2016, Creekside offers fun learning opportunities for children. Programs with the zoos animal ambassadors occur at the Discovery Theater. These programs feature insects, reptiles, mammals, and birds. Creekside also features a playground and boardwalk that over looks Emigration Creek.[51]

Princess Alice, a female Asian elephant, was the zoo's most famous and biggest attraction during the early 1900s. She came to the zoo, which at the time was located in Salt Lake City's Liberty Park, in 1916. Schoolchildren donated nickels and pennies to raise $3,250 to buy Princess Alice from a traveling circus called Sells-Floto Show Company. She was a big hit among Utahns. In 1917, a year after her arrival, the zoo built a building to house her in. Princess was the biggest draw for the small Salt Lake City zoo.

Princess Alice with her son Prince Utah in 1918

On April 29, 1918, Princess Alice gave birth to a male named Prince Utah. Utahans were thrilled with the news as he was the first elephant to be born in Utah. However, he died a year later on March 14, due to injuries he suffered after his mother rolled over him.

Utahans were upset after Princess Alice repeatedly broke free from her enclosure. This prompted the zoo to relocate. The Hogle family donated 42 acres of land at the mouth of Emigration Canyon in 1931. In July of that year, the zoo built its new elephant building with a safer and larger exhibit for Princess Alice. The building was dedicated to the children of Salt Lake City. The zoo opened later that year on August first. On August 14, 1932, a relief carving of Princess Alice was unveiled. It was donated by J. R. Fox, a local Utah sculptor.

In 1947, Princess Alice went on a rampage throughout the zoo grounds. She ripped up concrete, fountains, and an elm tree. After a few hours, she calmly returned to her exhibit. In 1953, Princess Alice was euthanized after becoming ill at the approximate age of 69. Princess Alice is one of the most famous animals in the zoo's history. She played a vital role in Utah's history as well.

Shasta, Hogle Zoo's famous liger

Shasta, who was born on May 6, 1948, was one of Hogle Zoo's most famous animals. She was the first liger born in America. Her mother was Daisey, a tiger, and her father was Huey, a lion. The two had been raised together, and that was why the zoo was able to breed them. Shasta weighed just over a pound at birth. However, her mother rejected her, and therefore she was hand raised. Shasta was a huge draw at the zoo. She was the reason for the zoo's success during the mid-1900s. Without her, Hogle Zoo might have gone out of business. Every year, the zoo held birthday parties for her. This drew in large crowds. After she died in 1972, she was sent to a taxidermist to be stuffed. Her body can now be seen at the Monte L. Bean Life Science Museum at Brigham Young University. At 24 years, Shasta holds the world record for the longest-lived liger in history.[52]

Gorgeous, a female western lowland gorilla, was one of the zoo's most famous animals. Gorgeous came to Hogle Zoo in 1985 from the Cheyenne Mountain Zoo in Colorado. She was caught in the wild in 1949 when she was only an infant. Gorgeous was very popular among guests, as she constantly interacted with them. However, Gorgeous lived alone because she did not get along with other gorillas. Therefore, she never had any offspring. In 1990, Gorgeous became world-famous as she was the first gorilla ever to receive cataract surgery. Dr. Allan Crandall, an ophthalmologist at the University of Utah Medical School, performed the surgery and implanted a lens into Gorgeous's eye. Gorgeous died in 1999 at the age of 50 and was the oldest living female gorilla at the time. She died of age-related problems. A bronze bust of the beloved animal was made in her honor attached with a plaque in both English and braille which can still be seen near the outdoor ape exhibits today.

Dari lived to be the oldest living African elephant in the world. She lived to the age of 55 and died due to age-related problems. Dari was loved by guests and staff alike. She was known for her caring attitude toward the other elephants in her herd.

Daphne was the oldest living giraffe in the world. She came to Hogle Zoo in 1985 from the San Diego Zoo Safari Park. She had nine calves at the zoo. Daphne died at the age of 31, which is double the average lifespan for giraffes.[53]

In the 1960s concern grew for the dwindling population of America's symbol the bald eagle. The species was declared an endangered species in 1967 after DDT poisoning had decimated North America's population. Reintroduction efforts were needed to help bolster the remaining wild individuals. Sam and Betsy, Hogle Zoo's mated pair in the Woodland Edge exhibit had successfully produced fertile eggs in 1989, 1990, and 1991. All three of their chicks were determined good candidates for release as their genetics were not well represented in wild populations. The 1989 chick was released in Arkansas and the 1991 chick in Georgia. The chick from 1990 was unfortunately lost to predation from a red fox after its release.[61] Without the banning of DDT in 1972 and reintroduction efforts made by organizations like Utah's Hogle Zoo, the bald eagle would have not recovered and been taken off the endangered species list in 2007.

The golden lion tamarin, a small New World monkey, has lost all but two to five percent of the species' original habitat in Brazil. The first population estimate in 1972, found between 400-500 golden lion tamarins left. From 1984 to 2001, an extensive effort to reintroduce the species to its native habitat took place involving 43 institutions in eight countries.[62] Utah's Hogle Zoo was one of the institutions involved in this effort. On April 29, 1993, Hogle Zoo sent Bagel, a male Golden lion tamarin, to the Smithsonian's National Zoo's former Center for Biological Research for a quarantine period in preparation to be released into the wild. On February 4, 1994, Bagel was introduced into the Poço das Antas Biological Reserve in southeastern Brazil, one of three small areas left in the wild that are home to the critically endangered species. [63]

On May 1, 1991, twin female black-and-white ruffed lemurs, a critically endangered species from Madagascar, were born at Hogle Zoo's former Primate Building. Born through a recommendation made by the Species Survival Plan, the twins were well-represented genetically in the North American population and therefore were considered good candidates for release into the wild. After seven years of being raised by their parents at Hogle Zoo, the two females began their journey to rewilding. On June 2, 1998, they arrived at the Duke Lemur Center in North Carolina where they joined four more lemurs that planned to be released to the wild. They spent around four months at the Duke Lemur Center where they had little contact with humans to help prepare for life in the wild. After completing the necessary training at the center, the twins, who had been named Dawn and Jupiter, were flown to the Betampona Reserve in the Atsinanana Region of Madagascar on October 27, 1998. After completing a standard quarantine, they were released alongside the four other lemurs into the natural reserve on November 25, 1998, helping to boost the critically endangered species' numbers.[64]

The boreal toad is an endangered subspecies of western toad found in alpine wetlands of the western United States. The species has suffered a decline over the last twenty years due to habitat loss and a fatal fungal disease. Hogle Zoo opened their Boreal Toad Conservation Center in 2015. The center housed eggs from the subspecies that were collected from the wild. The plan was to raise the eggs to adulthood, breed them, then release their offspring into restored habitats. In August 2021, Hogle Zoo released 21 boreal toads onto the Paunsaugunt Plateau in southern Utah from those that had been bred at the zoo's center.[65][66]

In 2014, Hogle Zoo's northwest end was transformed into Rocky Shores (see above). This three acre site was once home to exhibits like Bear Grotto, Penguin Cove, and the African Savannah, as well as habitats for Chacoan peccary, mountain lion, red panda, and llama.

In the late 1950s, the zoo constructed an exhibit for cougars. Large red cement rocks were made to mimic their natural habitat in southern Utah. The zoo's two cougars were orphaned brothers. Snow leopards were held in the exhibit while construction was being completed on Asian Highlands.

Chinook and her twin polar bear cubs Alcor and Mizar in Bear Grotto in 1999

Bear Grotto opened in 1958. The exhibit, reminiscent of Carl Hagenbeck's designs of the late 1900s, was intended for the zoo's polar bears and Kodiak bears. The two habitats, each 40 by 60 feet, had 15 foot deep moats separating guests from the bears and extensive rockwork. Bear Grotto's first inhabitants were a male and female polar bear pair. The two were born in the wild in Canada's Northwest Territories. The polar bears moved to Hogle Zoo on March 28, 1957, in preparation for the exhibit's opening. The male and female cubs were named Klondike and Kate via a contest in which a seven year old boy won a trip to Disneyland with his parents.

Klondike died in 1978 and the Kate in 1985. The zoo was hopeful for cubs and brought in Bubba, a male from the Oregon Zoo in 1978 and Chinook in 1979 from the Memphis Zoo where they were born respectively. The two proved to be a successful mated pair. Chinook welcomed her first cub, a female, on November 4, 1985. With Bubba, Chinook gave birth to a male in 1987, twins Aurora and Bubba in 1989, and a male Denali in 1993. Chinook's mate Bubba died on December 22, 1993, due to pancreatitis.

Due to Chinook's success as a mother, the zoo was looking to find a new mate for her. On June 23, 1995, the zoo welcomed Andy from the Buffalo Zoo where he was born in 1989.[67] The next year, Chinook gave birth to male twins Koluk and Kiska on November 19, 1996.[68] Two years later she had another set of male twins named Alcor and Mizar.[69] Chinook's last cub, a female named Anana, was born on December 12, 2000. It was decided to not allow Chinook to become pregnant again due to her age. Chinook was described as a protective defender and gentle, nurturing caregiver. The zoo's special bear mother was euthanized on December 18, 2002, after keepers had been monitoring escalating health problems.[70] Chinook was one of the most prolific polar bears in North American zoo history giving birth to a total of ten cubs. Currently she is survived by Denali who lives at the Sapparo Zoo in Japan and Kiska at the ABQ BioPark. However, many of her grandchildren still populate U.S. Zoos.

In 2003, Andy died from an intestinal blockage after swallowing a glove that was thrown into his exhibit. The blockage caused a rupture in the intestinal wall, leading to leakage of intestinal contents and fatal blood poisoning.[71] The zoo would not go on to bring polar bears back into their collection until the opening of Rocky Shores in 2012.

In July 2002, Dale, a female black bear, went on display in Bear Grotto. She was an orphan that was rescued from Minnesota. In 2003, Cubby, a male black bear, moved to Hogle Zoo from the Chahinkapa Zoo in North Dakota. Then in 2004, Tuff, a male black bear, came to live at Hogle Zoo. Tuff was born at a private breeder's farm in Missouri. He was then sold illegally. However, he was confiscated by officials and moved to a licensed facility. Tuff moved to Hogle Zoo shortly after. All of the black bears were moved to the Oregon Zoo because Hogle Zoo was going to start construction on their Rocky Shores exhibit.[72]

In July 1962, construction of a mountain habitat was completed in between the Bear and Cougar Grottos for aoudad, also known as Barbary sheep. The exhibit was originally home to five members of the sheep native to Northern Africa - one male and four females. They arrived via rail from Fresno, California, where they were purchased for $50 each. The exhibit was home to a plethora of animals over the years before its demolition in 2010.

In 1974, Hogle Zoo received its first two stone sheep, a subspecies of Dall sheep found in Canada and popular in big game hunting. The pair, only a year old upon their arrival, were born at the Okanagan Game Farm where then zoo director LaMar Farnsworth had a connection. At the time of their display, Hogle Zoo was the only zoo in the United States to exhibit the subspecies. The herd, which began to grow in size through births and other acquisitions, took up residence in the Mountain Habitat. When the zoo's herd began to die off, the final member, an elderly male affectionately named "Stone Sheep", was moved to the desert bighorn sheep exhibit on South Rim. The exhibit then became a summer habitat for the zoo's Aldabra tortoises.

Chacoan peccaries were the last species to inhabit the exhibit before it was demolished for the construction of Rocky Shores in 2010. The four new peccaries made their debut in 2004 on the Fourth of July. The all male group consisted of Walker and Palito from the Saint Louis Zoo as well as Chili Pepper and Habanero from the Phoenix Zoo.[73] The four males moved to the Woodland Edge exhibit in Discoveryland in 2010 before permanently leaving the zoo's collection in 2012 when construction began on the African Savanna.

Jane Goodall at the dedication ceremony for the zoo's new African Savanna exhibit on April 29, 1986.

While on a book tour for her text on the chimpanzees of Gombe, famed anthropologist Jane Goodall made a stop at Utah's Hogle Zoo to dedicate the zoo's new African Savanna exhibit on April 29, 1986. Joining her for the ribbon cutting ceremony was Utah Governor Norman H. Bangerter. In her remarks, Goodall commended the exhibit, noting her approval of the animals' ability to roam in an open space in social groupings.

The African Savanna covered one acre of the northwest section of the zoo, replacing chain-linked yards that once held many species including blackbuck, common eland, sitatunga, and wallaroo. The tiered exhibit featured three habitats for African ungulates and birds. Boma (enclosure) inspired fencing and a rondavel inspired indoor holding area added to the exhibit's authenticity. The $250,000 exhibit was funded through private donations and membership subscriptions. The African Savanna was demolished in 2010, when construction began on Rocky Shores at the west end of the zoo.

The African Savanna was split into three habitats. The Lower Savannah habitat was built as a new exhibit for the zoo's African antelope, including South Africa's springbok and Thomson's gazelle. New species were also added to the collection in the new African Savanna including addra gazelle and waterbuck. Cuvier's gazelle were added in 2002, and the critically endangered addax was added to the exhibit in 2003. The Lower Savannah habitat was visible via an outlook that extended from the path towards the old Giraffe Building as well as an elevated walkway that provided a birds-eye-view of the habitat.

The zoo added addax to the exhibit in 2003

The Upper Savannah was a habitat for plains zebra originally, until 1998 when they were replaced with Grévy's zebra. A gully provided a natural barrier between the guests and the zebras. The pond of this habitat trickled down into a waterfall that extended into the Lower Savannah. A third habitat for smaller antelope was located adjacent to the Sea Lion Pool. This space was later used for the addition of red pandas in 2002.

Egyptian geese and a flock of helmeted guineafowl had free range between the Lower and Upper Savannah habitats.

On November 9, 1998, Taji and Monty, two male Grévy's zebras arrived at Hogle Zoo from the Sedgwick County Zoo in Kansas. The two zebras occupied the Upper Savannah habitat. Their addition to the zoo's collection was significant, as it was the first time this endangered species had been exhibited in Utah.

On January 26, 2010, Taji was found dead in his barn. The following day, Monty was showing signs of distress. Later that day, it was determined that Monty needed to be humanely euthanized. For months, the zebras' deaths remained a mystery. Since it had snowed the week of their deaths, it was ruled out that any predators or humans had been involved. Both had experienced nosebleeds and blunt force trauma, possibly pointing to a fight between the two males.[74] On March 17, 2010, the zoo announced that the zebras' necropsy had come back inconclusive.[75]

To do this day, Taji and Monty's deaths remain one of the biggest unsolved mysteries in the zoo's history.

After the zebras' death and before construction of Rocky Shores, three male ostriches took residence in the Upper Savannah habitat. They moved to the former cheetah habitat just south of the Giraffe Building alongside the Egyptian geese and an elderly springbok before moving to the new African Savanna in 2016.

Hogle Zoo had a long history of exhibiting and breeding African penguins. In 1983, the first penguins arrived at Hogle Zoo. The four penguins were exhibited in a habitat outside of the Small Animal Building. On September 16, 1987, the zoo's first penguin chicks hatched. The same pair would go on to have three more chicks over the next three years. These chicks, however, did not live long and by the end of 1993, only one male from the colony was left.

On March 24, 1993, six African penguins, one male and five females, arrived at the zoo from the Maryland Zoo joining the zoo's lone male. This new colony would go on to produce 11 chicks from 1994 to 2007.

In 1996 the Sea Lion Pool, located in the northwest end of the zoo, was renovated to house the growing penguin colony. The Sea Lion Pool, originally built in 1964, was dedicated to former zoo director Gerald deBary who had died earlier that year from a fatal bite by a puff adder. The exhibit which was once home to harbor seals and California sea lions, was closed due to costly renovations required to meet standards for marine mammals. The exhibit needed a new filtration system which would have cost $500,000. Instead the exhibit was renovated and turned into Penguin Cove which opened to the public on October 24, 1996. The renovations, which cost $40,000, included a rocky coastline surrounding the existing pool, a nesting beach, and an indoor habitat.[76]

African penguins lived at Penguin Cove until the fall of 2010 when construction began on Rocky Shores. The remaining penguins were relocated to other accredited facilities including Dallas World Aquarium, Little Rock Zoo, and Toronto Zoo. The zoo has not had penguins in their collection since and has no plans for their return.

On December 6, 2002, Sarah and Ethel, two female red pandas made their debut in a new exhibit near Penguin Cove. The two had arrived the October prior from the Erie Zoo. The outdoor exhibit featured large trees for the red pandas to climb and an indoor habitat for them during Utah's hot summer months.[77]

Red pandas were absent from the zoo after November 2010 when construction began on Rocky Shores. The species returned in 2018 with the opening of a new exhibit in Asian Highlands.

The original 1968 scheme for the two-story Giraffe House designed by Bruce J. McDermott and Associates included space for African antelope and bird species.

In 1969 the unique two-story Giraffe Building was constructed. The giraffe building was not safe. In the early 1990s, two giraffes were euthanized after breaking legs on slippery floors. In 1994, the USDA cited the zoo because it failed to maintain structures in good repair at the Giraffe Building. The zoo was also cited in 1994 after failing to correct previously identified violations of peeling paint that could be ingested by the giraffes. In 2002, Sandile, a 7-year-old male reticulated giraffe, died after getting his neck stuck in a fence. In 2004, Ruth, a 26-year-old female reticulated giraffe, was euthanized after complications of a fractured leg. The zoo could not identify whether the broken leg was related to the building. Several giraffes died at Hogle Zoo, however, not all were building related. The zoo paid in all $50,000 to ensure that the Giraffe Building was USDA approved. After the African Savanna was opened in 2014, all of the zoo's giraffes were moved to a new state-of-art giraffe house. The old Giraffe Building was turned into the zoo's Maintenance Building, and it no longer houses animals.

Hogle Zoo's Feline Building in 1971, featuring two outdoor exhibits for lions and tigers.

In 1968, 4,750 Salt Lake City voters approved a $1 million bond for a major development project at Hogle Zoo. Then zoo director LaMar Farnsworth said that this was, "the greatest thing that has happened to the zoo". The bond would be used to help fund a transformation of the undeveloped southwest portion of the zoo. The first phase of the project included a new Feline Building, which would replace dated exhibits for the zoo's cat collection in the old Lion House.

The $340,000 Feline Building opened to guests on April 4, 1970. The exhibit consisted of five large concrete cages for big cats including Amur tiger, Bengal tiger, African lion, African leopard, snow leopard, and jaguar over the years. Large garage doors were open during the summer to let fresh air into the exhibit. The exhibit also featured two outdoor habitats for the lions and tigers. A series of smaller cages were home to an impressive collection of small cats including jaguarundi, ocelot, margay, Geoffrey's cat, clouded leopard, Asian golden cat, caracal, serval, sand cat, and African wildcat over the years. The most famous of the residents inside the Feline Building, however, was Shasta the liger who was born at the zoo in 1948. Shasta resided in the Feline Building for two years until her death in 1972.

African lions Flip and Abby in the zoo's Feline Building in the early 2000s

The Feline Building also included restrooms, educational displays, and a maternity cage for a mother cat and her offspring.

In 1995, the Feline Building began its first major renovation since its opening. The renovations, totaling $1,400 when completed in 1996, included fabricated trees, rock work, recirculating water, as well as murals depicting the species' natural habitats.[78]

The Feline Building closed in 2005, when construction started on the Asian Highlands. The skeleton of the Feline Building was retained, and now serves as the indoor holding areas for the Asian Highlands residents.

A 1973 rendering of the Hippo Building on the site where the Conservation Carousel is located today.

In 1973, zoo officials announced that Salt Lake County had pledged $130,000 for a new exhibit that would display the first hippos seen in Utah. A year later, the Hippo Building, or "Hippodrome", opened in 1974. The exhibit, which was designed by architect firm McDermott and Associates, included a 90 by 64 foot indoor building as well as a 90 by 40 foot outdoor habitat for both hippopotamus and pygmy hippopotamus. The construction, which cost a total of $235,000, consisted of six pools for the hippos, the largest of which was 30,000 gallons. A bridge connecting the north side of the zoo to the Hippo Building provided improved circulation for zoo guests.

On March 28 1974, the first residents of the exhibits, pygmy hippo pair Cleo and Brutus, arrived from West Africa. The pair produced three calves while living in the Hippo Building including a male in 1982, another male in 1983, and finally, a female in 1984. Brutus died at Hogle Zoo on April 10, 1997, while Cleo was transferred to Omaha's Henry Doorly Zoo on a breeding recommendation on October 27, 2001. Cleo died two days later.

Winston, the first pygmy hippopotamus born at Hogle Zoo on February 14, 1982, is seen with his caretaker Daisy Garcia.

On June 9, 1974, Tuff-Enuff, a male river hippo who was later named Moe, arrived from the Calgary Zoo. His mate Henrietta, arrived a day later from the Denver Zoo. The pair had two unsuccessful births in 1978 and 1979. Both calves died the day of their birth. Henrietta died on February 15, 1980 at the zoo. Moe was transferred to the Albuquerque Biological Park on April 11, 2005, where he still resides. Moe moved to join two females on a breeding recommendation.[79] Since moving to the ABQ BioPark, Moe has fathered three healthy calves, most recently a female in 2021.[80]

The Hippo Building also provided additional exhibit space for the zoo's African penguins as well as summer exhibits for the zoo's crocodiles and alligators. Also on display, in the exhibit was the zoo's famous "Museum of Human Stupidity" which featured objects from guests that had been found in animal exhibits throughout the zoo.

The Hippo Building was replaced by the Conservation Carousel which opened in 2008 as part of the zoo's Oasis Plaza.

In 1981, for the Hogle Zoo's fiftieth anniversary, the Animal Giants Complex was built. The exhibit was built to house the zoo's elephants, Dari, Kali, Twiggy, Toni, and Toka, and the zoo's white rhinos, Princess and George. Naturalistic outdoor enclosures were not only built for the zoo's pachyderms but for ostriches and tortoises too. The Animal Giants Complex was renovated for Elephant Encounter which opened in 2005.

Central Zone was located in where the current Meerkat Manor and lion holding facility are today. Central Zone was once home to the zoo's original elephant house known as the Main Building which was dedicated on July 31, 1931. The Main Building was not only home to the zoo's elephants including the famous Princess Alice, but a majority of the zoo's collection. On August 14, 1932, a relief of Princess Alice was unveiled on the front of the building which was donated by local sculptor J.R. Fox. The Main Building underwent many renovations, starting in 1945, to accommodate better living conditions for animals. By the late 1970s, most animals in the Main Building had moved to new exhibits within the zoo. At this point, the east side of the Main Building was renovated into an auditorium. As part of the Primate Forest exhibit, the west side of the building was renovated for indoor exhibits for the zoo's tufted capuchins and golden lion tamarins in the late 1990s.

Central Zone was also home to the zoo's Bactrian camel herd. By the early 2000s, the zoo had a successful breeding herd with at least one calf born every year. During the summer of 2012, Gobi, an arthritic male, was euthanized due to his pain. He lived with another camel, named Mabel, who was then sent to the San Diego Zoo to be with other camels and so the zoo could start construction on the African Savanna exhibit.

Entrance to Discovery Land in 1988

The first phases of Discovery Land opened in 1988 featuring a newly planted forest, duck pond, and fort for children to play in. A couple months after its opening, the George S. and Dolores Dore Eccles Foundation granted Hogle Zoo $100,000 as a matching grant. Combined with $700,000 from the Utah Legislature, the zoo had enough resources to fund new phases for the Discovery Land project. The new exhibits, which would transform the eastern end of the zoo, would display animals in naturalistic settings. North American animals were to be displayed in habitats representing woodlands, wetlands, and deserts. Under the direction of zoo director LaMar Farnsworth, the exhibits would cater to the zoo's younger demographic and include a new playground.[81] In 1990, Woodland Edge, Knoll and Burrow, and the Marsh were added to Discovery Land with Desert Canyon being added in 1992.

Woodland Edge was made up of four habitats that housed a series of raptors and cats over the years.

Tukut, a male bobcat who came to live in the zoo's Woodland Edge exhibit from the Living Desert Zoo and Gardens in 2002

Species exhibited in Woodland Edge included Canada lynx, bobcat, bald eagle, rough-legged hawk, and ferruginous hawk.

In order for construction on Rocky Shores to begin, some of the animals from the construction zone had to be moved to Discoveryland. The four exhibits in Woodland Edge were renovated into two larger habitats to accommodate the zoo's two mountain lions Kota and Echo as well as the zoo's four Chacoan peccaries. New exhibits were built for the bald eagles and bobcat who were occupying Woodland Edge on the zoo's South Rim.

Knoll and Burrow was completed alongside Woodland Edge. The two exhibits cost $275,000. The innovative exhibit resembled a cave on the American prairie. On the outside, visitors could see exhibits for common North American including a colony of black-tailed prairie dogs, yellow-bellied marmot, North American porcupine, striped skunk and rabbit.

The exhibits were also used to house more rare species. Utah's Hogle Zoo was the only facility to exhibit the rare Utah prairie dogs. In 1900 it was estimated that there were 95,000 Utah prairie dogs. In 2004, the Utah Department of Wildlife Resources estimated only 4,022 Utah prairie dogs left.[82] Their decline has been largely impacted by habitat loss. Hogle Zoo was working with government agencies in helping to preserve the endangered species.

In the early 2000s, Hogle Zoo participated in the Species Survival Plan for black-footed ferrets. The species was thought to be extinct until the discovery of a small population in northeast Wyoming in 1981. Biologists captured the last 18 known wild ferrets in 1986 to start a breeding program. Hogle Zoo served as a holding facility for ferrets that were non-breeding animals and for those that could not be released into the wild. A total of 10 black-footed ferrets called Knoll and Burrow home.

Inside the cave were exhibits for a cacomistle, southern flying squirrel, and a colony of over 200 Seba's short-tailed bats. Terrariums in the cave held blind cave fish and giant hairy scorpion. Inside the cave, guests could look through plexiglass to get up-close views of the outside exhibits.

The Marsh Aviary, was phase four of Discovery Land. Guests could walk out onto a boardwalk over the pond. In the pond, the zoo kept a group of injured American white pelicans, a breeding pair of mute swans, a greylag goose, and a snow goose. Also in the pond were other North American duck species. Visitors could pay twenty-five cents to feed the birds.

Desert Canyon was the fifth and final phase of Discovery Land. Large red stone rocks were constructed of fabricated rock, lath and rebar over three concrete and block buildings. A concrete gun was used to build a reddish-color cement-like compound, which was then hand-troweled for the rock-like appearance.[83] The construction of Desert Canyon cost $600,000.

As visitors entered the exhibit they followed a somewhat narrow path to two exhibits for small carnivores. Overtime many species were housed in these habitats including kit fox, ocelot, and white-nosed coati. Two Island foxes were also displayed here in the early 2000s which at the time were only exhibited at Hogle Zoo and the Santa Barbara Zoo.

Next visitors saw a collection of smaller exhibits for animals including Merriam's kangaroo rat and an aquarium which housed native Utah fish species June sucker and Bonneville cutthroat trout. Desert Canyon featured a recreated Anasazi cliff dwelling which provided views to a small mesa for angora goat and Navajo sheep.

Other small glass exhibits featured an array of species over the exhibit's timeline including Harris's antelope squirrel, white-tailed antelope squirrel, rock squirrel, nine-banded armadillo, southern three-banded armadillo, screech owl, long-eared owl, American kestrel, ring-necked pheasant, Bullock's oriole, and raven.

Desert Canyon also featured a building for the education department's animal ambassadors and a small amphitheater where animal programs were held.

Discovery Land closed in 2012 in anticipation of the new African Savanna. Before construction started, several of Discoveryland's animals were relocated to different areas of the park. An old angora goat and the Navajo sheep moved into the old desert bighorn sheep exhibit on South Rim. Tukut the bobcat and bald eagles Sam and Betsy moved to new exhibits on South Rim as well. The cacomistle and Seba's short-tailed bat's relocated to the Small Animal Building.

Tropical Gardens was a 3,300 square-foot temperature controlled greenhouse built in 1995 that housed several temporary exhibits at Hogle Zoo. The 40-by-80-foot glass enclosure was manufactured in New York. The exhibit replaced exhibits for otters and pheasants and ultimately cost $430,000. Tropical Gardens' first exhibit was Butterfly World which opened on June 10, 1995. The exhibit featured hundreds of butterflies representing 21 different species.[84][85]

In 1999, Jack, the Komodo dragon debuted in Tropical Gardens. On loan from Zoo Miami, Jack was over seven feet long and 150 pounds.[86]

On June 19, 2000, Baringa and her son Bundaleer, two koalas on loan from the San Diego Zoo made their debut in a new exhibit Wonders from Down Under. The two koalas traveled from the Salt Lake City airport to the zoo in a limousine. The celebrity status didn't stop there for the koalas. Eucalyptus was flown in from Florida twice weekly to feed the animals while they were on exhibit through October 8, 2000. Wonders from Down Under also featured laughing kookaburras and stick insects.[87]

Butterflies returned to Tropical Gardens in 2001.[88]

Possibly the most popular exhibit in Tropical Gardens was Outback Adventure which ran in the summer months for three years from 2002 through 2004. The exhibit featured around 350 free-flight birds from Oceania including budgerigar, cockatiel, eastern rosella, Papuan eclectus, salmon-crested cockatoo, and zebra finch. The exhibit, which debuted on May 4, 2002, had a $1 entry fee. For an extra $1, guests could purchase a stick with food for the birds to come and feed from. Outback Adventure also featured blue-tongued skink, bearded dragon, and white's tree frog.

Butterflies returned for a final time in 2005 and 2006.

On May 5, 2007, the zoo debuted Ghost of the Bayou, an exhibit featuring Antoine, an all white alligator. The 9-foot and 220-pond alligator got his coloring from a genetic mutation called leucism. Antoine was one of 18 white alligators found in the wild in a nest outside of New Orleans in 1987. Because of their unique pigmentation, their chances of survival were low and were therefore taken to the Audubon Zoo where Antoine was on loan from. The rest of the exhibit featured other animals from America's wetlands including baby American alligators, cottonmouth, spotted salamander, and American bullfrog.[89] The exhibit's popularity allowed it to return with Antoine in 2008.

2009 saw the opening of Madagascar! and the first time fossa, Madagascar's largest carnivore were seen in Utah. The exhibit featured two of the unique predators as well as lesser hedgehog tenrec, Madagascar tree boa, Madagascar hissing cockroach, and radiated tortoise.

The final exhibit to debut in Tropical Gardens was 2010s Nature's Nightmares featuring "scary" animals with important roles in their ecosystems. The stars of the exhibit were two king vultures. A colony of fifty free-flying straw-colored fruit bats from the Milwaukee County Zoo roosted above guests' heads. Terrariums held emperor scorpion Vietnamese centipede, dung beetle, goliath bird-eating spider, leeches, and red-bellied piranha. Other species within the exhibit were Norway rat and striped skunk. The exhibit returned in 2011 when it was renamed Living Links.[90]

From 1995 to 2011, Tropical Gardens was home to a number of some of the zoo's most popular exhibits and animals. The exhibit permanently closed in September of 2011 when construction began on the Beastro, the zoo's main restaurant. Many of the temporary exhibits' supplementary animals stayed in the zoo's collection and were housed in the Small Animal Building including the colony of straw-colored fruit bats.

During the summer months, a number of special temporary exhibitions have been hosted at Hogle Zoo. These attractions ranged from animatronic dinosaurs to conservation themed art.

Hogle Zoo has featured several animated dinosaur exhibitions. The two most recent being Zoorasic Park (2011) and Zoorasic Park 2 (2015).

In 2013, Creatures of Habitat featured 32 Lego sculptures by Sean Kenny depicting life-size animal scenes including Humboldt penguins, polar bears, and golden lion tamarins.[91]

Fourteen animatronics depicting various supersized bug species were scattered around zoo grounds in Bugszilla during 2017. The exhibit worked to help destigmatize the creepy-crawlies and helped educate guests on the important roles insects play in ecosystems.[92]

Angela Haseltine Pozzi's Washed Ashore came to Hogle Zoo when fifteen of her sea-life sculptures were displayed in 2019. Each sculpture is made of recycled plastic that was collected from United States shorelines. The artwork educates viewers on the importance of recycling and reducing plastic waste as well as the effect pollution has on marine life.[93]

Every year during the late winter, the zoo hosts the World of the Wild Art Show. This indoor exhibition shows animal-themed art by various artists.

The Great Ape and Primate Forest expansion will be the biggest project Hogle Zoo still has to undertake. The project will modernize the exhibit space for the zoo's gorillas, orangutans, and smaller primates. As part of the plan, the zoo hopes to exhibit different species together. For example, the zoo wishes to introduce its colobus monkeys in with the gorilla troop. Another plan combines the zoo's spider and howler monkeys in with other South American species like tapir and capybara. This idea of mixed-species exhibits will not only stimulate the animals, but it will give guests an idea of how these animals live in the wild. Primates and apes travel long distances in the wild. Therefore, another plan for the expansion is to have overhead chutes connect several exhibits to allow the animals to move to different exhibit spaces. This feature would give the animals choice as they would have in the wild. The Great Ape and Primate Forest expansion will also allow better viewing opportunities for the guests.

The Diversity of Life and Education building will be the zoo's new Small Animal Building. Located where the old Beastro and RendeZoo building are today, the new exhibit will feature the animals from the Small Animal Building as well as new small animals. The current Small Animal Building was built in the 1970s and is dated. The new building will have better space for both animals and guests.

The building will be three stories high. The first two stories will be dedicated to animals. The third floor will be used by the education staff. On the south side of the building, there will be a three-story rain forest exhibit featuring free-ranging primates and birds. Other possible exhibits may include a Madagascar exhibit. Funding for the exhibit has already begun and the project was originally scheduled to be done by 2022 but has yet to begin construction.

After the current Small Animal Building is demolished, the zoo will build a new building that will feature traveling exhibits. When the new Beastro restaurant was built in 2014, the Tropical Gardens exhibit, which featured the zoo's traveling exhibits, had to be destroyed. The new building will be bigger than Tropical Gardens. This will allow for larger traveling exhibits

The Asian Highlands expansion will include minor renovations to the current Asian Highlands exhibit as well as construction on more exhibits above Asian Highlands. Better exhibits for the zoo's Asian goats as well as exhibits for other Asian species will be a part of the construction. The construction will also include improvements to the South Pathway.
