Providence petrel
The providence petrel (Pterodroma solandri) is a large and heavy build gadfly petrel that nests in two locations in the Tasman Sea: Lord Howe Island (some 800 km from the Australian mainland) and Philip Island.

This bird was once numerous on Norfolk Island, however an estimated 1 million birds were harvested for food, and was completely exterminated on this island by 1800.[2] It was also threatened by the introduction of mammalian predators in the late 18th century.[3]
This species is classified as least concern. However, the providence petrel is deemed to be in a precarious position because its breeding is confined to two mountain tops and one tiny islet, and is therefore at great risk from a catastrophe.
Graceful and supple in flight, the providence petrel has a cumbersome propensity on the ground, making it vulnerable to attack by predators. Main in causes of death are predation by the endangered Lord Howe rail and flooding of burrows. Other dangers include rat predation and drowning in longline fishing gear. The current population is estimated at only 64,000.
Some populations are diurnal, while others are nocturnal. This may be a result of different foraging areas or historical predators that are no longer present.[3]
The scientific name of this species was given in honour of the Swedish botanist Daniel Solander, with Solander's petrel being an alternative common name.
