Tangara de Rieffer Chlorornis riefferii

Large, bulky tanager found in the upper subtropical and temperate zones of the Andes from Colombia to Bolivia. Striking and not likely to be mistaken: entirely bright green with red bill and legs and rufous face and undertail coverts. Fairly common in montane forests and edges, where singles or pairs often move slowly with mixed-species flocks. Forages at all levels. Listen for its distinctive nasal call notes.
