Bamboo bear

Iconic black-and-white bear of the mountain bamboo forests of central China, giant pandas can weigh up to 125 kg and spend up to 14 hours daily consuming bamboo, which comprises 99% of their diet despite belonging to the order Carnivora. Solitary and elusive, they have a pseudo-thumb for gripping bamboo stems. Downgraded from Endangered to Vulnerable in 2016 following successful conservation and breeding programs.

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.
