About These Birds
Black-backed Grosbeak
The Black-backed Grosbeak is a large, striking finch found along forest edges and scrubby montane slopes on the eastern Andes from Colombia to Bolivia and Argentina. Males have a black back and head with golden-yellow underparts and a massive bill. It feeds on seeds, berries, and insects, often foraging in the canopy.
