Schwalbentangare Tersina viridis

Unique small tanager, widespread in lowlands and foothills up to 1,800 m. Male is bright cerulean with a black mask, white lower belly, and some black bars on the sides. Female is mossy green with paler yellow belly and scalloped barring on the sides. Behavior much different from other tanagers: perches upright, often on exposed branches or treetops, and sallies out for insects like a flycatcher. Usually seen in pairs or small loose groups. Found at forest edges, clearings, or gardens.
