First records of the wing-barred seedeater, Sporophila Americana (Gmelin, 1789) (Thraupidae), for acre and a revision of its distribution in the Brazilian Amazon

Abstract

We present the first records of the Wingbarred Seedeater (Sporophila americana) in Acre, Brazil. These observations, together with the published records and the specimens housed in museum collections, indicate that S. americana occurs over a considerably larger geographical area than is currently presented in the relevant literature. The occurrence of S. americana in the region of São Paulo de Olivença, in the Brazilian state of Amazonas indicates the potential existence of a sympatric zone with the congener Caqueta Seedeater (Sporophila murallae) in the western Amazonia.
