Small, warbler-like tanager of tropical lowlands. Favors forest edge, woodland, and semi-open areas with taller trees. Often occurs in small groups, sometimes larger flocks, usually in the canopy of flowering trees, where it probes for nectar with its long bill. Red legs are bright on male, dullest on young birds. Male in blue in breeding plumage, with a turquoise cap; female and non-breeding male are greenish overall with faint streaking on the chest. In flight, the underside of the wings flash bright sulphur-yellow.
