Canastra) e Distrito Federal. Habita savanas e campos com gramíneas altas. Sua distribuição é ampla e apesar de sujeita ao declínio da qualidade do habitat devido à agricultura e pecuária, a espécie é mais resistente à degradação ambiental do que outros congêneres e não há evidências de que a perda de habitat possa atingir um nível de ameaça de extinção em um futuro próximo. Desta forma, S. pileata foi categorizada como Menos Preocupante (LC).

“…O acompanhamento de 83 ninhos no estado de São Paulo, entre 2012-2017, indicam que o tamanho da ninhada varia entre 1-3 ovos. Os ninhos são construídos com gramíneas e teias de aranha e possuem formato de taça (Freitas et al, 2018). Geralmente bastante comum na maior parte de sua distribuição.…”

“…Sporophila bouvreuil is distributed from Suriname and French Guiana to central and northeastern Brazil, down to western Minas Gerais and eastern São Paulo state [20,21]. Their nests are small deep cups (~6 cm in diameter), built mainly of grass stems, placed in herbaceous vegetation of open floodable areas, 15-70 cm above ground [22]. Clutch sizes consist of two eggs (rarely three), and like all of the Sporophila, they are socially monogamous and males are highly territorial during the breeding season [16,22].…”

The small Neotropical finches called capuchinos are outstanding because they have experienced one of the most recent and explosive avian radiations ever documented for birds. Despite very low morphological and niche divergence among species, many of them are reproductively isolated when in sympatry due to strong sexual selection in plumage traits. However, a specific pair of mostly parapatric species, the Pearly-bellied, Sporophila pileata, and the Copper Seedeaters, S. bouvreuil, has confounded taxonomists because individuals with intermediate color patterns can be found. By analyzing diagnostic COI mtDNA sequences and adult male plumage we provide evidence for hybridization. Paternity tests using microsatellites also indicated that representatives with intermediate plumage pattern can be fertile. Our findings are consistent with the classification of S. bouvreuil and S. pileata as distinct taxa, but we demonstrate that the sexual selection mechanisms involved in the isolation of other reproductively sympatric capuchinos are not applicable to this pair of species, likely because of reduced barriers to mate recognition.
