The chestnut seedeater is a species of bird in the family Thraupidae. It is found in Argentina, Brazil, Paraguay, and Uruguay.
Region
Southern Cone of South America
Typical Environment
Occurs patchily in lowland grasslands, wet meadows, and the margins of marshes and lagoons across Argentina, Brazil (especially the south), Paraguay, and Uruguay. Prefers tall, seeding grasses and sedges, often in lightly grazed or recently flooded fields. During the non-breeding season it can shift locally to drier pastures with abundant seed heads. It uses scattered shrubs or fence lines as song perches. Habitat quality is closely tied to traditional pasture management and seasonal flooding.

A small grassland tanager of the capuchino seedeater group, the chestnut seedeater favors wet meadows and marshy edges in the Southern Cone. Males show rich cinnamon tones that can make identification tricky among similar Sporophila species. The species is threatened by loss of native grasslands and trapping for the cage-bird trade. Conservation of seasonally flooded pastures and controlled grazing regimes benefits this bird.
Temperament
shy and discreet in tall grass
Flight Pattern
short rapid wingbeats with low, undulating flights
Social Behavior
Typically in pairs during the breeding season, with the male singing from exposed perches on grasses or fences. Outside breeding, forms small, loose flocks that may mix with other seedeaters. Nests are small open cups placed low in dense grasses or herbaceous cover. Both habitat availability and grass seeding cycles influence local presence.
Migratory Pattern
Seasonal migrant
Song Description
The male delivers a high, tinkling series of thin notes and brief trills, often repeated from a perch. Calls include soft chip and tsip notes given in flight. Song can vary among individuals and is similar to other capuchino seedeaters.
