アカチャツグミマイコドリ Schiffornis major

Fairly small, orange-brown bird of forest midstory. Darker brown wings, and a variable amount of gray in the head. Found in tall forest in seasonally flooded and riverine areas, and forages singly or in pairs, not usually joining mixed-species flocks. Similar to some attilas, but has a shorter tail and a shorter, stubbier bill. Listen for its distinctive high whistled song, “tuw-tuwee . . . tee, tuweep!”
