Rainbow-bearded Thornbill

One of the most colorfully named hummingbirds, rainbow-bearded thornbills display a distinctive long, multi-colored gorget — glittering from green to blue to violet — in a uniquely elongated beard-like pattern. They inhabit open páramo grassland and scrub at very high Andean elevations from 3,200–4,500 meters in Colombia, Venezuela, Ecuador, and Peru. Among the highest-altitude hummingbirds, they forage on low-growing páramo flowers and are adapted to sub-zero night temperatures through nocturnal torpor.
