Mindanao Brown-Dove
Phapitreron brunneiceps
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. Similar to White-eared and Amethyst Brown-Doves, but Mindanao lacks the black-and-white stripe below the eye. Sings an accelerating series of identically pitched notes, “wup-pup-pup-pu-pu-pu-pu,” reminiscent of a ping-pong ball falling on a table.

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".<p>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. Generally brown-colored, these medium-sized birds have a glossy reddish-violet patch on sides of the neck and warm, dark brown upper parts. 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.<p>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. It is very distinct from the Tawitawi brown dove as it is much darker and lacks the peach of the Tawitawi brown dove.<p>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.

保护状况
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. It is not clear if the species makes seasonal or altitudinal movements, but both are considered likely on a local scale.<p>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. 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.<p>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.<p>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.

Appert's Tetraka
Xanthomixis apperti
Pretty, medium-sized tetraka. Green back, gray head, and rich yellow underparts. Rare and localized Madagascar endemic that is found in a handful of forest patches in the southwest. Most often seen in the understory of western deciduous forest. Often in pairs, small flocks, or mixed-species flocks. Call is a series of silvery, sputtered “spit” notes. In its small range, separated from Spectacled Tetraka by its brighter underparts, gray head, and pale eye-stripe. Much smaller and more brightly colored than Long-billed Bernieria.
Spot-throated Woodcreeper
Certhiasomus stictolaemus
A small and difficult to identify woodcreeper, widespread but often rare and seldom encountered. Smaller than most other woodcreeper species in range (slightly larger than Olivaceous Woodcreeper), with a relatively short, straight bill and weakly marked brown plumage. Note the faint pale streaking on the head and spots on the throat. Best found and identified by voice, a fast, even trill lasting between 1-2 seconds and usually heard at dawn.
Southern Tropical Pewee
Contopus cinereus
Small, gray flycatcher lacking strong markings. Note its peaked crown and yellow lower half off bill. Some birds may show faint wingbars and a slight yellowish cast to the belly. Little overlap with other pewees; in the Andes it might be found together with Eastern Wood-Pewee or Western Wood-Pewee during the northern winter. Southern Tropical Pewee has shorter wings, a longer tail, and may show a faint spot between the bill and eye. Voice is the most reliable way to separate them. Listen for an explosive “CHIpeer” as well as a series of sharp chip notes. Typically encountered at forest edge or in clearings. Often perches on an exposed branch, from which it flies out to chase insects in looping, acrobatic sallies.
