Large, striking tanager of tall rainforest. Combination of size and blue-and-yellow plumage is diagnostic; female is more extensively yellow below, including on face. A generally uncommon resident of undisturbed forest regions; may also be found in shorter-stature forests on sandy soils, but is generally absent from disturbed and coastal areas. Usually seen with mixed-species flocks in the canopy. Hops clumsily among branches, gleaning insects from foliage. Distinctive, far-carrying call is two-noted, the second lower-pitched.
