Olive-capped Coua

A tiny, bright green parrot found throughout much of the Amazon basin. Dusky-billed has darker green plumage and a dark upper bill compared to the very similar Blue-winged Parrotlet. Dusky-billed is also less likely to be found around clearings than Blue-winged. Often first noticed by the incessant high-pitched, buzzy calls given by flocks, not as high-pitched and piercing as the calls of Blue-winged.

Large, distinctive hummingbird. Superb male is mostly red and essentially unmistakable; female best told by large size and mostly green plumage with orange outer tail feathers. Found in lowland forest, usually along blackwater creeks in forests with sandy soils. Nests on low vegetation overhanging water. Very noisy and aggressive in territorial defense; loud, smacking calls are often heard before the birds are seen.

Small, strikingly-plumaged antbird with a long tail and a very restricted range. Inhabits the understory of low stature or regenerating forests, forest edges, scrub, and abandoned plantations where it is very active and occasionally joins mixed-species flocks. Much plumage variation, with coastal males near Rio de Janeiro (formerly split as Restinga Antwren) being almost uniformly sooty-black with only slightly grayer back and spotted white wingbars. Two more northerly subspecies vary between rufous-brown and dark gray above, but both are black below with a bold white eyebrow and white wing spots. In all subspecies, females are pale whitish below and brown above with a bold white eyebrow. Male song is a monotonous series of harsh chip notes; female gives nasal squeaks.
