Sinaloa Crow

A large owl of lowland and foothill forest, including secondary habitat and plantations. Warm brown with a heavily marked back, a heavily streaked rufous head and chest, and a more sparsely streaked pale belly. Note the square-shaped head with flattened ear tufts and the yellow eyes. Unmistakable. No other owls of similar size occur in its range. Gives a long, drawn-out, spooky whistled note whose pitch rises slightly, then falls at the end.

Tiny, boldly-colored flycatcher. Compact and short-tailed; yellow below, black above, with a white throat and mustache, and small red shoulder patch. Found in secondary forest, especially with tall bamboo, in a limited range along the foothills of the Andes in southern Peru. Its chirping musical song is often duetted.

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.
