Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Métallure arc-en-ciel

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.
