About These Birds
Blackish-blue Seedeater
The Blackish-blue Seedeater is a small, dimorphic finch; males are uniform dark slaty-blue to blackish while females are warm brown with a pale bill. It inhabits bamboo thickets and dense scrub within Atlantic Forest and adjacent areas in southeastern Brazil, Paraguay, and northeastern Argentina. It specializes in feeding on bamboo seeds but also takes other grass seeds and small insects.

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.
