The Thick-billed Seed-Finch is pretty abundant in Fincas Bambuzal, Rio Frio. They can be found all around the grass and forest edge, feeding on grass seeds primarily, but also on seeds from flowering plants. The male is black with a barely visible white patch on the wings, while the female is brown in coloration.
