The Chestnut-capped Puffbird is a relatively small member of the genus Bucco, from which the family Bucconidae is named. Its small size, bright chestnut cap and black mask and breast band distinguish it from all other puffbirds. It is found throughout western Amazonia from Colombia and southeastern Venezuela south to northern Bolivia, usually found in “edge” situations, typically along streams, or by clearings in seasonally flooded forest. Like other species of puffbird, typically found in pairs, and often seen perched in the mid-story for long periods of time. It forages by sallying out and grabbing insects from vegetation. Call is a single mournful whistle, repeated frequently, not dissimilar to the call of a Dusky-capped Flycatcher (Myiarchus tuberculifer).
