White-vented Shama

Nest parasite that lays its eggs in the nests of Jameson’s Firefinch. Breeding males are glossy purplish-black, with a pale brownish panel in the wings, while females and non-breeding males are streaky and brown on the back and pale below, with a bold facial pattern. The bill is whitish and the legs very pale pink. Found in forest edge, cultivation, thick woodland, and scrub. Mimics the vocalizations of its host firefinches: a fast trill. Extremely similar to Variable Indigobird. In South Africa, separated by its pale pinkish legs. Elsewhere, breeding males probably slightly more glossy but only separated with certainty by hearing mimicked vocalizations of host species.

A distinctive small cuckooshrike with a striking, deep rufous underside, a white eyebrow, and extensive bold white markings in wings. Upperside is black in males, gray in females. Juveniles show a rusty-tinged eyebrow and rust-edged upperpart feathers. Found in pairs or small groups in the canopy. Occurs in most environments with trees, including forests, mangroves, sparsely wooded areas, and gardens, most often in the lowlands but also in the foothills. Calls include strident “pips” and chirps, often given repeatedly. Song is a rapid series of piping notes.

Common raptor in open spaces in the high Andes and southern South America. Large, relatively broad-winged, and short-tailed raptor. As the name suggests, plumage is quite variable. Adults range from clean white to dark gray and rufous below with a gray or rufous back. Always look for the white tail with a black band near the tip. Juveniles are more confusing, usually dark brown above and buffy below with a variable amount of dark streaking below. Juveniles can also be all dark brown (but this morph is rare). Compare with Black-chested Buzzard-Eagle, which is larger and broader-winged, with young birds usually darker than most Variable Hawks. Occurs from sea level up to over 4,500 m in the Andes, typically in open agricultural land, desert, or paramo, but also ranging over wooded areas.
