Mindanao brown dove

Ebird describes it as "A medium-sized dove of forest from the lowlands to middle elevations in the mountains. Dark brown above, with a brown head, purplish iridescence on the back of the neck and upper back, grayish underparts, pale buff under the base of the tail, and a pale gray tail tip".[2]

Adults look similar to amethyst brown dove and white-eared brown dove but are distinguishable by a brown crown, vinous-gray belly, buff undertail-coverts and less olive back.[3] Generally brown-colored, these medium-sized birds have a glossy reddish-violet patch on sides of the neck and warm, dark brown upper parts.[4] Additional distinguishing features include a slightly darker nape compared to the crown, a narrow dark streak under the eye, black bill, dark pink feet with brown nails and iris that is orange-red in color.[5]

Based on size, the amethyst brown dove is the largest of the three, followed by the Mindanao brown dove and the white-eared brown dove being the smallest.[6] It is very distinct from the Tawitawi brown dove as it is much darker and lacks the peach of the Tawitawi brown dove.[7]

Its call is an accelerating series of identically pitched notes, "wup-pup-pup-pu-pu-pu-pu", reminiscent of a ping-pong ball falling on a table.[2]

It occurs in tropical moist lowland forest and tropical moist low-montane forest typically at a range of 900 to 2,000 meters above sea level but there are sparse records way below at 150 m. It occurs in humid interiors and dense secondary forest.[7] It is not clear if the species makes seasonal or altitudinal movements, but both are considered likely on a local scale.

IUCN assessed this species as vulnerable and estimates the population to be 2,500 to 9,999 mature individuals. Consideredl rare in range Threats include habitat loss and hunting for both food and the exotic pet trade.[8] Illegal logging is not as rampant at high elevations, because most trees are not commercially valuable and the slopes are too steep to be converted to farmland. However, mining, both legal and illegal, are prevalent.

It occurs in a few protected areas including Mount Kitanglad National Park, Mount Apo Natural Park, Mount Malindang National Park and Moun Hilong-hilong. Mount Matutum has been proposed as a national park. However as is the case in most of the country, deforestation and hunting still occur in these areas as protection is lax.

Conservation actions proposed include to survey to assess abundance, elevational range and habitat requirements at key sites and to assess whether the species is present in poorly surveyed areas of Mindanao Ensure the effective protection of remaining forest at key and potential sites.[9]
