It has been suggested that this southeast Brazilian endemic is either a hybrid swarm between Yellow-bellied Seedeater (Sporophila nigricollis) and Double-collared Seedeater (Sporophila caerulescens), or alternatively a localized color morph or variant of the first-named species. Certainly, its plumage somewhat resembles one or both, or is intermediate between them. Males have the mantle grayish with a black hood contrasting with the white rear underparts. Females are presumably indistinguishable from those of Yellow-bellied Seedeater at least. Males conforming to this description have been found to at least 800 m in the states of Bahia, Espírito Santo, Minas Gerais, and Rio de Janeiro, usually in areas of scrub and grassy vegetation, much like those occupied by other, similar seedeaters.
