Sooty Grassquit

Small plain vireo of tropical forest and woodland in lowlands. Usually stays fairly high in trees and likely to be overlooked unless its rather tuneless, monotonously repeated song is learned. Identified by a combination its gray head (in Mexico and Central America) with a diffuse whitish eyering; whitish underparts with a yellowish wash on the sides; and plain olive upperparts. Head of birds from eastern Panama to South America is olive, with a whitish eyering.

Fairly small and typically plain greenbul. The pale bill and legs are unusual. Also note the pale whitish or orangish eye. Found in the thick undergrowth and mid-story of forest. Usually in small, vocal groups. The distinctive call is an accelerating series of nasal barking notes. Similar to several other greenbul species, but separated by the pale bill and legs. Further separated from Cabanis’s Greenbul by the lack of yellowish tones on the underparts.

Attractive rock-thrush in which males and females are strikingly different. Males have a gray head and back and rufous underparts, while females have a brown, heavily scalloped head and back and mostly white underparts. Found very locally in miombo broadleaf woodland. The song consists of musical, vibrating whistles. Similar to migratory Rufous-tailed Rock-Thrush, but male lacks white back and female has little or no scalloping below.
