Blue-gray Tanagers Visit Butterfly On Panama Fruit Feeder – Aug. 21, 2018
Watch a pair of Blue-gray Tanagers join a butterfly on the Panama fruit feeder platform. These soft-colored tanagers are a ubiquitous species of the humid tropic lowlands. They typically travel in pairs or small single-species flocks, briefly joining mixed-species flocks at fruiting trees.

The Panama Fruit Feeder Cam is a collaboration between the Cornell Lab of Ornithology and the Canopy Family.
I saw these beautiful blue-grey tanagers in Costa Rica and in Suriname.
