Orange Bullfinch

Large, terrestrial bird of lowland forest; unlike anything else in range. Appears all dark with paler belly; note long tail, heavy bill, and bare red skin around eye. Uncommon and shy; usually seen alone, on or near the ground, fleeing swiftly on foot at the slightest disturbance. Follows army ant swarms and herds of peccaries to prey on insects and small vertebrates flushed by the animals’ activities. Frequently snaps bill in alarm or while foraging. Far-carrying song is a single, gruff hoot, somewhat recalling Zigzag Heron, repeated at long intervals.

Large and distinctive tanager of scrubland, open woodland, and Polylepis in the high Andes form NW Argentina to La Paz, Bolivia. Similar to Saltators, which it was formerly considered part of, but note extensive rufous underparts, and slate gray back and chest.

A spectacular harrier patterned in black and silvery white. The male is distinctive with black head, striking yellow cere and eyes, and black shoulders, breast, and wingtips, contrasting with its silvery-white underparts and forewing. The female is gray-and-brown above and lighter below, with a small white rump. Females superficially resemble female Pallid and Montagu’s Harriers, but have a paler underwing with narrow dark barring and sparse streaking on underwing coverts. The species hunts by quartering suitable habitat on buoyant wings. It eats mostly small mammals, amphibians, reptiles, and insects.
