koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.

Slate-colored Grosbeak

A large, heavy-billed seed-eating bird of humid lowland forest in the Amazon basin, Central America, and northern South America, slate-colored grosbeaks have uniform dark slate-grey plumage with a powerful, pale bill. Despite their name, they are placed in the saltator genus. They inhabit dense, humid forest interior and forest edge, foraging in pairs or small groups on large seeds and hard fruits. Their powerful bills crack seeds too tough for most other birds. Listed as Least Concern.
