Caspian Snowcock

Plump fruit-eating bird with uncertain taxonomic affiliations. Shape, small bill, and plumage are distinctive. Male is mostly black above with yellow rump, dirty yellow chest and flanks, and gray belly. Female is olive above with gray head and contrasting black cap. Feeds on fruit in montane forests, usually singly or in pairs. Slow-moving, often sitting still. Limited range.

Often draws attention to its presence by its song: an ascending sequence of “kwa” notes, similar to Green-backed Trogon, but faster. Two subspecies occur in Brazil, Paraguay, and northeastern Argentina with limited geographical overlap that vary in the color of the breast and eyering; the southern one has a red belly and eyering, while the northern one has a yellow belly and eyering. The males of both subspecies have a violet-blue head and breast, a green back, and a white undertail. Females have a dull gray breast and the undertail is gray with white tips. Found in the middle to upper levels of forests and woodlands.

A fairly large raptor of lowland and montane forest. Brown above with a heavily streaked chest, a barred belly, a fairly long flattened crest coming from the back of the head, and piercing golden eyes. In flight, note barred, bulging wings and fairly long barred tail with a broad terminal band. Juveniles are much paler. Remarkably similar to Philippine Hawk-Eagle, but in flight Philippine Honey-buzzard has a narrow head which projects more from the wings. Voice consists of a drawn-out, two-noted “weeeeeeee lew” repeated at intervals.
