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.

Tawny-bellied Hermit

A large hermit hummingbird of humid Andean foothill forests in Peru, Ecuador, and Colombia, tawny-bellied hermits have warm tawny-buff underparts contrasting with greenish-bronze upper parts and a long, strongly curved bill. Found at elevations between 300–1,500 meters in montane forest understory. Like all large hermits, they are trap-line foragers visiting long routes of widely spaced flowers. Males assemble at traditional lek sites where they produce loud, repetitive vocalizations to attract females.
