Épervier à collier roux

The Collared Sparrowhawk, known scientifically as <em>Accipiter cirrocephalus</em>, is a small bird of prey belonging to the family Accipitridae. As a member of the genus Accipiter, <em>Accipiter cirrocephalus</em> is characterised by its short, rounded wings and long tail, adaptations that enable agile manoeuvring through forest and woodland habitats while pursuing bird prey. The species typically inhabits forests, woodland, and forest edges, where it hunts small birds and occasionally insects. It is reported to occur in Norway according to available range data. Adult males of this species often display a distinctive rufous collar on the nape, which contributes to the species' common name. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Sparrowhawk is currently assessed as Least Concern on the IUCN Red List.

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.
