Appearance
The adult brown-capped vireo is 12–12.7 cm in length and weighs 12 g. It has olive-green upperparts and a brown crown. There is a brown line from the bill through the eyes, and a white supercilium. The face and throat are off-white, and the underparts are otherwise yellow with some olive on the flanks. Young birds are buff-brown above with a weaker supercilium.
Behavior
The brown-capped vireo has a sharp "twiist" call and the song is a rich warbled "here you see me hear me sing so sweet", reminiscent of that of the warbling vireo.
Habitat
This vireo occurs in the canopy and middle levels of light woodland, the edges of forest, and other semi-open habitats at altitudes from 500 to 2500 m. Brown-capped vireos feed on caterpillars and other insects gleaned from tree foliage. They also eat small fruits. They will join mixed-species feeding flocks.References:
