Rufous-headed Pygmy-Tyrant
Pseudotriccus ruficeps
Tiny, plump flycatcher found in the understory of subtropical and temperate cloud forest in the Andes. Not likely to be confused. Bright rufous head, wings, and tail contrast with olive back and breast. Belly slightly paler yellow. Sexes similar. Flits around the understory in singles or pairs, usually within forest. Best detected by its bill snaps or descending rattle call.

Speckle-breasted Wren
Pheugopedius sclateri
A distinctive medium-sized wren found from central Colombia to northwestern Peru. Occurs from sea level to around 1,600 m, locally higher. Warm brown above with a white eyebrow, streaked black-and-white face, and black spotting on breast. Tail and undertail coverts have strong barring. Pairs are found in the dense understory of scrubby woodland and edges. Listen for the loud sweet song phrases and the distinctive call, like running your finger up a comb.

Wattled Curassow
Crax globulosa
Very large black gamebird with a red bill. Males have a white ventral region which is chestnut in females. Strongly associated with riparian environments, especially seasonally flooded forest and river islands, where it is quite arboreal. Now very rare over much of its range because of overhunting.
