About Sporophila palustris (Barrows, 1883)
The marsh seedeater, scientifically named Sporophila palustris (Barrows, 1883), is a bird species that belongs to the family Thraupidae. This species shows sexual dichromatism: males have a distinct appearance with a bright white throat, grey crown, and chestnut belly, while females look similar to other brown female seedeater species. It is distributed across Argentina, Brazil, Paraguay, and Uruguay. It is a migratory species: it breeds in wet grasslands and marshes located around Uruguay and Argentina, then migrates north to wet and dry grasslands in southern Brazil during the austral winter. This species is currently threatened by three main factors: habitat loss, trapping for the pet trade, and pesticide use. It receives legal protection across most of its range, and a number of existing protected areas help to safeguard its population.
