Black-and-white Seedeater

A small, boldly patterned seedeater with striking black-and-white plumage in males — jet black upper parts and wings contrasting with white underparts — black-and-white seedeaters inhabit open and semi-open habitats including grassland, forest edge, and plantation shade in the Andes from Colombia to Bolivia. One of the more distinctively patterned Sporophila seedeaters. Females are plain brown and buff. They forage on grass seeds and are sometimes kept as cage birds for the males' patterning and song.

Ruddy-breasted Seedeater

A tiny, chestnut-red seedeater of open grasslands, weedy fields, and marshes distributed across Central America and most of South America east of the Andes to Argentina, ruddy-breasted seedeaters have warm rufous-red plumage in males with darker wings. Among the most widely distributed Sporophila seedeaters, they thrive in disturbed agricultural landscapes and secondary growth. They forage in small to large flocks on grass seeds and cereal crops. Least Concern with populations benefiting from agricultural expansion.
