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.
Identification
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.

Other Birds
Acre Antshrike
Thamnophilus divisorius
Secretive, rare medium-sized antshrike of the dense forests of the Cordillera Divisor of remote western Brazil and eastern Peru. Males are dark gray with a bluish tint to the back and upperparts, while females are bluish-gray above and brownish-orange below. Inhabits the lower levels of forests, where it is more often heard than seen; voice is a fast series of notes increasing in speed before finishing with a final higher note.
Eurasian Blackcap
Sylvia atricapilla
A rather distinctive and bulky warbler: male plain grayish overall with eponymous black cap; female and juvenile plain, slightly browner overall, with rusty-brown cap. Inhabits wooded and scrubby habitats, including gardens, sometimes visiting feeders in the winter. Small numbers winter in Western Europe, but most migratory birds move south to Africa and the Mediterranean region. Song is a varied, rather loud rich warble, often strident. Often gives a harsh “chakchak” call, usually in series. Rare dark morph with black-hooded male and brown-hooded female can be found on the Atlantic Islands and very scarcely elsewhere.
Chestnut Weaver
Ploceus rubiginosus
Large, heavy-billed weaver in which breeding males have an unusual color scheme: chestnut with a black head. Non-breeding males and females are plain grayish-brown with buff on the breast. Highly nomadic species of dry savanna, which can appear in large numbers after rains and begin nesting in large colonies. Males are oddly similar to Chestnut Sparrow, and they often nest alongside that species, but are easily separated by their larger size and black head. Non-breeding male and female are remarkably colorless, lacking the greenish and yellowish tones shown by similar weavers.
