Breeding and feeding sites in its preferred marsh habitats are always disturbed by poachers involved in illegal pet trade. Overgrazing has also destroyed most of its native ecosystem.
The Marsh Seedeater, a migratory and sexually dichromatic bird species from the Thraupidae family inhabits the wet and dry marshlands of Argentina, Brazil, Paraguay, and Uruguay.
Adult males are recognised by its grey crown, white throat patch, and chestnut belly while adult females have physical features like other brown female seedeaters.
Its song can be heard frequently from behind the marsh-bound Eryngium flowering plant. It prefers its seed still on the stalks.
