Rufous-browed Chat-Tyrant

Rather large hummingbird of humid evergreen and pine-oak forest in mountains. Fairly common, but typically inconspicuous in shady understory and at edges, where feeds at all levels on flowers. Despite the exciting name, often looks rather drab and grayish overall with a dark mask, whitish eyestripe, and dusky throat (amethyst gorget rarely catches the light). Note the blackish tail with small, pale gray corners.

A medium-sized, long-legged, long-necked bustard. The male has a striking black face pattern and a black line down the neck that connects to the black belly. The female is much plainer. In flight, shows a mostly white wing and a black rump. An uncommon species of grassland and savanna. Male is similar to male Black-bellied Bustard, but separated by blacker face with a cleaner white mark on the cheek. Females are very similar, but Hartlaub’s has a pale line down the faintly speckled neck. In flight, Hartlaub’s also shows less black in the wing and a black rump. The male Hartlaub’s gives a click, a pop, and a moan, which sometimes precede a display flight in which he jumps up into the air and then parachutes down.

The only dipper in its range, and thus unlikely to be confused. Chunky and boldly patterned in blackish and white, with obvious white crown and underparts (somewhat variable in different parts of range). Sexes similar. A denizen of fast-moving streams and rivers with plenty of rocks to perch on. Fairly widely distributed in the Andes from Venezuela to Bolivia; can be found from 700–3,500 m. Usually seen singly or in pairs, quite conspicuous as they perch on boulders or fly along the river. Gives a piercing “dzeet!” call, especially in flight.
