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.

Ruddy-breasted Seedeater

A tiny, chestnut-red seedeater of open grasslands, weedy fields, and marshes distributed across Central America and most of South America east of the Andes to Argentina, ruddy-breasted seedeaters have warm rufous-red plumage in males with darker wings. Among the most widely distributed Sporophila seedeaters, they thrive in disturbed agricultural landscapes and secondary growth. They forage in small to large flocks on grass seeds and cereal crops. Least Concern with populations benefiting from agricultural expansion.
