The red-legged honeycreeper (Cyanerpes cyaneus) has striking blue breeding plumage with a turquoise crown, contrasting black wings and back, and bright red legs, though males adopt a duller, greenish eclipse plumage after the breeding season. This small bird, roughly 12 cm long, feeds on fruit, insects, and nectar using its long, down-curved black bill and is found in small groups in forests from Mexico to Brazil. A unique feature is the lemon-yellow underwing, visible only in flight. Males display brilliant violet-blue and turquoise breeding colors, but moult into a dull greenish eclipse plumage after the breeding season. Females are consistently green with a white eye stripe.
