Taxonomy

Subspecies

Three subspecies recognized[1], which do not overlap in range with each other.

  • A. c. relicta (Slate-blue Seedeater):
  • Mountains of southern Mexico (southern Jalisco to Guerrero, Morelos and Oaxaca)
  • A. c. concolor :
  • A. c. aequatorialis (Ecuadorian Seedeater):
  • Mountains of south-western Colombia (Nariño) to northern Peru (Cajamarca)

Subspecies relicta from Mexico west of Isthmus is sometimes split as Slate-blue Seedeater.[2] Gill and Donsker split aequatorialis as Ecuadorian Seedeater and name the remaining species Cabanis's Seedeater.

Habitat

They can be found in the undergrowth of tropical woodlands and forests, especially where bamboo grows.

Behaviour

Diet

Their main diet consists of seeds, particularly bamboo. Also insects and possibly leaf petioles of bamboo.
