Chapman's Bristle-Tyrant Pogonotriccus chapmani

Tiny flycatcher of tepui highlands. Appears plain olive-green above and pale yellow below, with bold buffy wing bars and longish tail. Generally uncommon in humid forest above 800 meters, where pairs or small family groups forage actively, sallying to foliage for insects, usually in terminal leaf clusters. Often found with mixed-species flocks. Vocalizations include a distinctive, two- or three-noted descending call, with a squeezed quality; may also give a high, thin rattling trill when excited. Unlikely to be mistaken for other species in its limited range.
