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.[1][2]

Taxonomy and species list

Perspective
The genus Amaurospiza was introduced by the German ornithologist Jean Cabanis in 1861 with Cabanis's seedeater as the type species.[3][4] The name is derived from the Ancient Greek amauros, meaning "dusky", and σπίζα (spíza), a catch-all term for finch-like birds.[5][6]
This genus was formerly included in the tanager family Thraupidae. It was moved to the cardinal family Cardinalidae based on a molecular phylogenetic study published in 2007.[7][8]
The following cladogram shows the phylogenetic relationships within the genus as determined by Juan Areta and collaborators in 2023.[2]
