Petit-duc de Marshall

The cloud forest screech-owl (Megascops marshalli) is a small owl in the family Strigidae endemic to the eastern slopes of the Andes in Peru and Bolivia, inhabiting cloud forest and humid montane woodland between approximately 900 and 2,200 meters elevation. Described scientifically in 1981, it belongs to the diverse Megascops screech-owl assemblage of the Americas. The species has brown, streaked cryptic plumage and small ear tufts typical of screech-owls, with a characteristic song used for territory advertisement in cloud forest habitats. It is nocturnal and insectivorous, feeding on large insects, small lizards, and other invertebrates caught in the forest understory. The cloud forest screech-owl has a restricted range on the humid eastern Andean slopes, where increasing deforestation for agriculture and coca cultivation reduces suitable habitat. Its population status is considered Least Concern given the continuing extent of Andean cloud forest in its range, though forest clearance on the eastern Andean slopes remains a long-term threat to this and many other narrowly endemic cloud forest bird species.

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.
