Band-tailed Antwren
Myrmotherula urosticta
Small, short-tailed antwren. Look for the broad white tail-tip. Males are gray with black bibs and wing coverts; females are light gray above and buff below. Found in humid forests, where it forages in the understory and at middle levels, usually together with mixed-species flocks. The song is a nasal series of clear “tjeuwi” notes.
识别特征
The band-tailed antwren is 9 to 10 cm (3.5 to 3.9 in) long. It is a smallish bird with a short tail. Adult males have gray upperparts with a hidden white patch between the shoulders. Their wings are gray with white-tipped black coverts. Their tail is darker gray with the eponymous wide white band at the end. Their throat and upper breast are black; the rest of their underparts are a paler gray than the upperparts. Adult females have a paler gray face and upperparts than males with white-tipped gray wing coverts. Their throat is white, their sides and flanks gray, and the rest of their underparts pale cinnamon-buff.

分布与栖息地
The band-tailed antwren is a bird of the Atlantic Forest. It found very spottily and locally in coastal eastern Brazil between Bahia and northern Rio de Janeiro state. The largest numbers are found in the southern Bahia-northern Espírito Santo area. It inhabits the understorey to mid-storey of evergreen forest and adjacent mature secondary forest in the lowlands. It appears to favor tall forest on sandy soil, especially those with abundant vines in their lower reaches. In elevation it occurs below about 500 m (1,600 ft).

Bahama Warbler
Setophaga flavescens
This charming species is fond of pine woods where it is often found creeping along branches and trunks in a manner similar to that of the Black-and-white Warbler. Also visits flowers. The very similar Yellow-throated Warbler has less extensive yellow on both belly and face as well as a thicker eyeline, more distinctive white patch behind the cheek, and shorter bill. Song is a sweet “chutty, chutty, chutty, swee, swee, tsoo, tsoo.” Call is a single high “chip” or “tsit” like that of a Yellow-throated Warbler.
Golden-breasted Fulvetta
Lioparus chrysotis
A stunning little bird, extremely brightly-colored for a fulvetta. Body is lit up by yellow undersides and sunny orange patches on the wings. Coal-black head with a white ear is reminiscent of Coal Tit, but rounder and crestless. Color scheme loosely resembles that of Silver-eared Mesia, which is much larger and has a more elongated body shape. Travels in large, noisy flocks through dense mid- to high-altitude forests.
Mottled Swift
Tachymarptis aequatorialis
Huge swift with powerful, falcon-like flight. Overall coloration is gray with a paler throat and mottling on the belly, but often looks blackish when seen in flight overhead. A darker, blackish population nests in Luanda, Angola, and wanders widely. Found over a wide variety of habitats, though often in the vicinity of rock outcroppings. Near breeding colonies, gives an exuberant trilled call. Similar in size and shape to Alpine Swift, but separated by the dark rather than white belly. Separated from all other swifts by large size.
