Crossley's Vanga
Mystacornis crossleyi
Brown-backed, babbler-like vanga of the forest understory. Male has a black hood, and female a white throat. Endemic to Madagascar, in eastern rainforest at low and middle elevations. Shy and elusive bird that walks along the forest floor and through thick tangles. Song is a long, penetrating whistle given from a low perch. Coloration and habits make it distinctive.
Identification
Crossley's vanga is a small babbler-like bird, 15 cm long and weighing around 25 g. Its most distinctive feature is the olive-grey bill, which is disproportionately long and slightly hooked at the end. The plumage of the male is olive green on the crown, back, wings, tail and flanks, a grey belly, black throat and face, with a white submoustachial stripe and grey stripe above the eye. The legs are grey and the iris black. The female is similar but with a white throat and belly.
Taxonomy
The bird is in the monotypic genus Mystacornis. The species is an example of convergent evolution: its bill and body shape adapted to its habit of looking for insect prey in the leaf litter, eventually becoming so similar to that of ground-babblers that early naturalists initially classified the Crossley's vanga into what was then known as the babbler family, Timaliidae.

Behavior
The breeding season for this species is from August to November. The male builds a shallow cup nest of twigs and rootlets in a tree or other vegetation around 1.5 m off the ground. Two to three eggs are laid and incubated by both sexes.<p>It forages singly or in pairs. It is a terrestrial bird that feeds on the ground on spiders, cockroaches, earwigs, true bugs, grasshoppers and ants. It rarely flies but instead walks and runs and probing its bill into leaf-litter, mosses, and soil.

Comb Duck
Sarkidiornis sylvicola
Large bicolored waterbird. Both sexes are iridescent purplish-green above with a white breast. Males have a large black lump on the bill, dark flanks and whitish belly, whereas females have a plain bill and gray flanks. Note all dark wings. Occurs throughout much of South America, rarely straying north to Costa Rica. Found in freshwater rivers, lakes, and marshes where it is usually uncommon. Normally silent.
Blue-throated Piping-Guan
Pipile cumanensis
Large, lanky, black and white bird of lowland rainforest. Note the bare, white face and white wing patches, which really stand out in flight. Crown and nape are also mostly white, but also streaked with buff. It has a fleshy throat patch that is typically blue, but it may be gray or black on some birds. Mostly arboreal, but sometimes descends to the ground to feed or drink. Song, often given at dawn or dusk, is a rising series of clear whistles. Occasionally rattles its wings loudly in flight.
Short-tailed Emerald
Chlorostilbon poortmani
Small, compact hummingbird found in extreme western Venezuela and central Colombia. Male is entirely glittering emerald with a dark tail. Female is greenish above with a grayer throat, a dark cheek, and a thin white eyeline. Occurs in various wooded habitats and edges, often feeding at flower patches at low or middle levels. Typically found at lower elevations than the very similar Narrow-tailed Emerald.
