The ruddy-breasted seedeater (Sporophila minuta) is a species of bird in the Emberizidea family. Although all Sporophila are small finches, Ruddy-breasted Seedeater is notable for being one of the smallest-bodied members of this genus. This also is one of the most northerly species of seedeater, and occurs from southern Mexico south to northern South America.
Male: mostly brownish gray above, wings and tail duskier with indistinct small whitish wing speculum; rump and entire underparts cinnamon-rofous, deepest on the throat. Female: buffy brown above, wings and tail duskier, feather with pale buff edging; below pale dule cinnamon to buffy brown.
Like other Sporophila, Ruddy-breasted Seedeater primarily forages on grass seeds in open habitats, and often forages in flocks outside of the breeding season.
The nest is a simple cup, but is notable because it usually contains a few stem grass stems that stick up above the rim of the cup.
