Grey Seedeater

A small, inconspicuous seedeater with grey-brown plumage and a conical bill, grey seedeaters inhabit open grasslands, savanna, and rice fields across northern South America from Colombia and Venezuela to Trinidad and the Guianas. Males are medium grey with darker wings; females are streaked brown. Highly gregarious, forming large foraging flocks on grass seeds. Like many grassland seedeaters, grey seedeaters are poorly known ecologically and face ongoing pressure from agricultural conversion of native grasslands.
