Appearance
The male is almost entirely black, with a small white wing patch. The female is a rich brown all over. They are both very similar to the all-black Caribbean slope form of the variable seedeater. It is distinguished, however, by a larger bill with a straight culmen. They measure 11.5 cm long and weight 13.5 g.
Naming
It is replaced by the closely related chestnut-bellied seed finch in South America east of the Andes, as well as the valleys of Cauca and Magdalena in Colombia. The two have often been considered conspecific as the lesser seed-finch.References:
