Yellow-browed Tyrant

Odd and distinctive terrestrial batis. Has long legs, an upright posture, and a white tail with a black dot near the tip. Found in dry woodland and savanna, often in rocky areas. Spends most of its time on or near the ground, though it will perch up in bushes. Usually in pairs. Vocalizations include piercing whistles, low croaks, and ratcheting calls. Similar to batises, but terrestrial habits and white tail easily identify it.

A small, chunky, distinctive weaver of northeastern Africa. Mostly sandy brown with a gray cap and a pale eye-ring. There is some geographical variation in back color, which can be brown or gray. The tail has a pale gray tip and a partial black bar across the middle, both of which are obvious in flight. Found in dry savanna and cultivated areas, usually in flocks. Nests in colonies. Gives a variety of inconspicuous calls, but one of the most frequent is a penetrating “veet.” 

Large, stout-billed woodcreeper of tall rainforest in northeastern Amazonia. Plumage entirely rufous-brown with no barring or streaking; note thick reddish bill, white throat, and prominent white whisker mark (bill of young birds is dark brown). Found in tall rainforest as well as slightly lower-stature forests on sandy soils; generally less common than other large woodcreepers. Climbs along tree trunks and large branches at middle and upper levels, probing bark crevices for insects and small vertebrates; occasionally follows army ant swarms to capture animals fleeing up tree trunks. Heard more often than seen. Song, given mainly at dawn, is a far-carrying, hoarse whistle repeated 3–4 times, very unlike other woodcreepers. Amazonian Barred-Woodcreeper, which also has a reddish bill and suggestion of a pale whisker, may occur with Red-billed at ant swarms and be mistaken for it in dim understory light; note Red-billed’s stouter bill and plain face with obvious whisker streak.
