Sayaca Tanager

Thraupis sayaca

The sayaca tanager is a species of bird in the family Thraupidae, the tanagers. It is a common resident in northeastern, central, and southeastern Brazil, and Bolivia, Paraguay, Uruguay, and northeastern Argentina. A few are recorded from far southeastern Peru, but its status there is unclear, in part due to the potential of confusion with the very similar juveniles of the blue-grey tanager. Source
