Brown-backed Needletail
Hirundapus giganteus
A very large swift with broad wings pinched at the base, a protruding front, and a bulky rear. Short tail has well-defined spines that can be seen even in fast flight. It has blackish-brown upperparts with a pale-brown saddle, often difficult to make out; the underparts from the throat to the lower breast are dark brown, ending in a well-demarcated deep “V” that contrasts strongly with the white belly, vent, and undertail. When seen well, it shows white lores, a feature absent in other large needletails. It has an extremely fast and powerful flight and hence can suddenly appear from nowhere and disappear quickly.
识别特征
The brown-backed needletail (Hirundapus giganteus), or brown needletail, is a large swift. These birds have very short legs which they use only mainly for clinging to vertical surfaces. They never settle voluntarily on the ground and spend most of their lives in the air, living on the insects they catch in their beaks. These swifts are resident breeders in hill forests in southern India and southeast Asia, extending to the Greater Sunda islands of Indonesia and Palawan in the southern Philippines. They build their nests in rock crevices in cliffs, laying 3-5 eggs. The flight is impressively fast, even compared to other swifts. The brown-backed needletail is among the largest swifts worldwide, and at 23 cm is bigger than the Alpine swift and the white-throated needletail. It has a similar build to the latter species, with a heavy barrel-like body. They are dark brown except for a white undertail, which extends on to the flanks. There are two subspecies, with the subspecies breeding in southern India (Brown-throated Needletail, H. g. indicus) distinguished from the nominate form, breeding in southeast Asia (H. g. giganteus) by white lores on the former. The Hirundapus needletailed swifts get their name from the spined ends of their tail, which is not forked as in the Apus typical swifts. The brown-backed needletail has more prominent tail spines than in other needletail species.

Prince Henry's Laughingthrush
Trochalopteron henrici
Handsome laughingthrush endemic to the southeastern Qinghai-Tibetan Plateau and its adjacent Himalayan foothills. Gray overall, with a dark rust-colored face, slate-blue-and-orange wing panels, and a bright white “moustache.” An adaptable species, occurring in and around human habitation, as well as naturally-occurring brushy and scrubby areas such as forest edges and gulches. In pairs or flocks, often foraging noisily in bushes or on the ground. Song consists of loud, bright, repeated “woop-di-dee-doo!” phrases, and calls include loud rattling series.
Black-capped Antwren
Herpsilochmus atricapillus
Small, long-tailed antwren of the middle to upper levels of woodlands and dry forests. Males are gray with a contrasting black cap and eyebrow. The tail is black and white-tipped and the wings are black with white bars. In females note the cinnamon forehead, gray back and buff belly. The song is loud and usually given as a duet.
Sumatran Wren-Babbler
Napothera albostriata
With its long curved bill, this uncommon Sumatran mountain forest endemic is unique within its limited range. Forages alone or in pairs, often in dense undergrowth where it can be difficult to see; listen for its song, a well-spaced series of even, clipped whistles that sound like they should be coming from a small owl. If lucky enough to catch a glimpse, look for a streaky dark brown body, very short tail, and bright white throat.
