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.
Identification
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.
Taxonomy
The band-tailed antwren was described by the English zoologist Philip Sclater in 1857 and given the binomial name Formicivora urosticta. The species is monotypic. The band-tailed antwren and the long-winged antwren (M. longipennis) form a superspecies.

Range and habitat
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).

Purple-throated Woodstar
Philodice mitchellii
Woodstars are tiny hummingbirds that fly like bumblebees. Purple-throated is restricted to the west slope of the Andes in Colombia and Ecuador, where it inhabits cloud forest, edges, and second growth from 800–2,000 m. Males have a glittering purple throat, white chest band, fairly long forked tail, and white patches on the sides of the rump. Unlikely to be confused within range. Females are trickier; note the orangey belly with a variable amount of smudgy white in the center (never as extensive as on female White-bellied Woodstar) and the thin whitish line that extends behind the eye and wraps around the neck (not as wide or buffy as on Little Woodstar). Often seen singly feeding in the canopy; visits feeders.
Golden Nightjar
Caprimulgus eximius
Small, pale nightjar of the Sahel zone. Plumage is a beautiful golden with silvery bands. Bold white wing patches and tail corners visible in flight. Nocturnal. Day-roosts on the ground under bushes. Inhabits semi-desert with low shrubs and scattered trees, often in rocky areas. Song is a repeated sequence of rapid disyllabic notes, "k-ku, k-ku, k-ku, k-ku…"
Black-chested Tyrant
Taeniotriccus andrei
Striking small flycatcher with a black crest. Has a chestnut head, a black breast band, and gray underparts. Males have a black back, females an olive back. Note the yellow feather edges to the wings in both sexes. Inhabits the understory of humid forest, dense second growth, and seasonally flooded forests, favoring areas with dense vine tangles or bamboo. The song is a series of low “chewp” notes interspersed with double “chewp-chewp” notes, easily mistaken for a frog or insect.
