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.

Green-tailed Trainbearer

A medium-sized Andean hummingbird with a long, deeply forked green tail — the longest tail relative to body size among trainbearer hummingbirds — male green-tailed trainbearers inhabit open grassland, scrub, and Andean hedgerows from Ecuador to Bolivia at elevations of 2,000–4,000 meters. Males perform aerial display flights with the ornamental tail streaming behind. Found in semi-open Andean landscapes including gardens, agricultural areas, and páramo edges where they feed at diverse flowering plants.
