The Double-collared Seedeater (Sporophila caerulescens), is a species of bird in the Emberizidae family. These birds include sparrows, New World sparrows, seedeaters, and their allies. It is found in Argentina, Bolivia, Brazil, Paraguay, Peru, and Uruguay; also the southern border of Colombia on the Amazon River. Its natural habitats are subtropical or tropical moist shrubland, pastureland, and heavily degraded former forest.
The species ranges from central Argentina east of the Andes cordillera northwards through Bolivia and Paraguay, and northeastwards into south-central Brazil, and southeast coastal Brazil; the species retreats into Amazonia during the austral winter. The Double-collared Seedeater is only found in the southern Amazon Basin, limited by the Amazon River as its northern limit.
It is a dimorphic species, with the male having a gray head and back, a black-collared throat, paired with a black band just below, across the upper whitish breast. It has gray legs, a medium length tail, and the stout bill for seed-eating. The female is less colorful.
