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.

Northern Cardinal

The northern cardinal is the state bird of seven US states, more than any other species. Unlike many songbirds, both males and females sing, often in duets. Cardinals do not migrate and their brilliant red plumage against winter snow makes them a favorite among backyard birdwatchers.
