The brown-capped vireo (Vireo leucophrys) is a small passerinebird. It breeds in highlands from southern Mexico south to northwestern Bolivia. It is sometimes considered to be conspecific with the similar warbling vireo.
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.
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.[citation needed]
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.[2] Brown-capped vireos feed on caterpillars and other insectsgleaned from tree foliage. They also eat small fruits. They will join mixed-species feeding flocks.
