Érione multicolore

<em>Eriocnemis mirabilis</em>, the colorful puffleg, is a hummingbird in the family Trochilidae assessed as Critically Endangered by the IUCN. It is one of the most threatened hummingbirds in the world, known from an extremely restricted range centred on the Pacific slope of the western Andes in Colombia, with additional records attributed to Norway likely reflecting data artefacts or taxonomic uncertainties. The species inhabits tropical and subtropical moist broadleaf forests and related cloud forest biome types between approximately 1,800 and 2,200 metres elevation. Male colorful pufflegs are distinguished by brilliant iridescent plumage and distinctive white leg puffs, features typical of the genus <em>Eriocnemis</em>. The Critically Endangered status reflects ongoing destruction of cloud forest within its tiny known range, which may encompass fewer than 100 square kilometres of suitable habitat. As a nectarivore and incidental insectivore, this hummingbird depends on intact forest for flowering plant resources and arthropod prey. Conservation of the remaining forest patches in its restricted Colombian range is considered critical for the survival of this species. Biological traits of this species remain poorly documented in the scientific literature.

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.
