分布与栖息地
It inhabits primary dipterocarp forest, typically on mountain slopes (although this may simply reflect a constraint enforced by forest loss), occasionally visiting isolated fruiting trees over 1 km from the nearest forest. It requires large trees for nesting. Whilst the species's diet mainly consists of fruit, small lizards and some insects may also be consumed.<p>IUCN has assessed this bird as critically endangered. In 2019 it was reported that only 27 mature individual hornbills are still believed to be alive in the wild. This makes it the most endangered hornbill and one of the most endangered animals in the entire world. It has gone extinct on the island of Jolo, due to hunting and the remaining populations in Tawi-Tawi are threatened by habitat destruction through logging and slash-and-burn farming.

Brown-breasted Pygmy-Tyrant
Hemitriccus obsoletus
Tiny flycatcher found in the understory of forests with bamboo. Plain olive-brown above and pale buff below. Note the buff spot in front of the eye. The similar Drab-breasted Pygmy-Tyrant has a white (not buff) spot in front of the eye and occurs at lower elevations than the Brown-breasted Pygmy-Tyrant. The song is series of “tic-tic-tic” notes.
African Chaffinch
Fringilla spodiogenys
Dapper little finch endemic to northern Africa, where it inhabits a range of habitats, from forested hills and canyons to coastal parks and gardens. Handsome male has a blue-grayish hood, bright white eye crescents, green back, pinkish throat and breast, and a black-and-white wing pattern (colors muted in winter). Female much drabber but shares male pattern; especially note the complex wing pattern. Both sexes have white outer tail feathers, often striking in flight such as when flushed. Song is a buzzy descending series of trills and rattles; calls include a somewhat sparrow-like “dwee!”
Yellow-eyed Black-Flycatcher
Melaenornis ardesiacus
Slim, long-tailed, all-black flycatcher with a pale yellow eye. Found along the edge and in clearings within Albertine Rift montane forest. Single birds of pairs perch out on conspicuous perches, sometimes quite low. Calls include low chuckling notes and a high, thin whistle; the song is a whispy, complex mix of high-pitched notes. Distinguished from all similar black birds by its pale eye.
