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.

Red-legged Honeycreeper

A small, strikingly colored tanager-related honeycreeper, males display vivid royal blue plumage with bright red legs — the diagnostic feature giving the species its name — and a long, curved, yellow-tipped bill. Found in tropical and subtropical forest canopy from Mexico south to Bolivia and Brazil, including Trinidad. They probe flowers for nectar, and their long bill accesses flowers unavailable to shorter-billed birds. Important pollinators of tropical canopy tree flowers. Common and widespread across humid neotropical lowland forests.
