Buff-cheeked Tody-Flycatcher

The buff-cheeked tody-flycatcher is about 9 cm (3.5 in) long. Adult males have a slate-gray forehead and forecrown with black spots and a dark olive hindcrown whose feathers extend slightly to a crest. Their face is mostly light pinkish cinnamon. Their back, rump, and uppertail coverts are bright olive. Their wings are blackish with pale edges on the flight feathers and yellowish white tips on the coverts; the latter show as two wing bars. Their tail is blackish. Their throat and breast are mostly white with thin dark streaks on the throat that become olivaceous on the breast; there they are blurrier but still distinct. Their belly is pale yellow with the breast streaks extending into its upper part. Their bill, legs, and feet are dark. The female plumage has not been described.

The buff-cheeked tody-flycatcher was long known only from the type specimen that had been collected in 1830 at Borba in Amazonas state. It was re-found there in 1993. In the early twenty-first century it was also found in another part of Amazonas and in Rondônia. The species inhabits humid stunted forest along black-water rivers and in low-stature woodlands on white-sand soil.

The buff-cheeked tody-flycatcher forages towards the top of vegetation regardless of its height. Nothing else is known about its diet or feeding behavior.
