Rotkehltapaculo

The Chucao Tapaculo (Scelorchilus rubecula) is a secretive, ground-dwelling bird in the family Rhinocryptidae (tapaculos), endemic to the temperate Valdivian rainforests of southern Chile and adjacent Argentina. This robust, short-tailed bird has rich rufous-chestnut underparts and a barred or mottled brown upperside, blending into the dense leaf litter and fern undergrowth of southern beech (Nothofagus) and mixed Valdivian forest where it lives. The species is named for its far-carrying, repetitive call — a loud series of notes that rings through the forest understory. It feeds on insects, spiders, and other invertebrates found on the forest floor. Despite being cryptic in behavior, the Chucao Tapaculo is locally common and conspicuous by sound within its range, which spans roughly from the Lake District of central Chile south to Tierra del Fuego. The IUCN classifies it as Least Concern, reflecting stable populations within intact Valdivian forest. Deforestation and conversion of old-growth forest to pine and eucalyptus plantations are the primary threats to the species' preferred habitat. The Chucao Tapaculo is a flagship species for temperate South American forest conservation.

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.
