Bamboo Seedeaters

Amaurospiza is a genus of seed-eating birds in the cardinal family Cardinalidae that are found in Central and South America.

These blue seedeaters are allopatrically distributed and show only small differences in plumage coloration and body measurements. They are sexually dimorphic in plumage: the male is slaty blue while the female is tawny brown. They favour bamboo thickets where they feed on buds, shoots and insects.
