Green Hermit

A large hermit hummingbird of humid rainforest in Central America and the northern Andes, green hermits are named for the males' predominantly green plumage — unusual among hermits which are generally brown and buff. Females have blue-green upper parts and rufous underparts. Found from Costa Rica to Peru and Venezuela at elevations up to 1,600 meters in forest understory. They are important pollinators of large Heliconia and Calathea flowers along the forest floor, following established trap-line routes.

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.
