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.

Black-thighed Puffleg

An Andean puffleg hummingbird named for the males' distinctive velvety black thighs contrasting with the characteristic white leg feather puffs, black-thighed pufflegs inhabit humid montane forest and forest edges in Ecuador and Colombia at elevations of 1,500–3,500 meters. Males display glittering green plumage with a violet-blue tail. Listed as Near Threatened due to deforestation of the Andean cloud forest, with populations declining as the specialized high-altitude forest habitat is cleared for agriculture.
