Sporophila bouvreuil

The Copper Seedeater is a passerine bird, and it measures about 4 inches. The males have a cinnamon coloration with black wings and tail, while the females have olive-brown upperparts and white-yellowish underparts.

The Copper Seedeater is commonly seen in fields with tall grasses, open savannas, and marshy areas. It lives in groups outside the breeding season, often alongside other species that also consume seeds. During the molting period, the plumage becomes faded. Clutches usually consist of 2 to 3 eggs, with 2 to 4 broods per season. The chicks hatch after 13 days.

Its distribution ranges from the estuary of the Amazon River (Amapá, Pará) and Maranhão to Rio Grande do Sul, encompassing the entire Northeast and Southeast, extending to Goiás and Mato Grosso, in Brazil. It's also found in Argentina, Paraguay, and Suriname.
