Common tanager, found in a variety of forest habitats. Usually seen from below, in which case it is best identified by uniform dark underparts with rufous lower belly and undertail coverts, and active behavior. The shining white rump can be seen from most angles on perched birds, even when high overhead. Found in tall rainforest, shorter-stature forests on sandy soils, and in disturbed areas. Groups move rapidly through treetops, usually with other species of small tanagers, feeding on fruit. Calls are indistinct chips, often given in rapid series in flight.
