Martin-chasseur à collier blanc

The Collared Kingfisher, known scientifically as <em>Todiramphus chloris</em>, is a widespread species of kingfisher belonging to the family Alcedinidae. One of the most broadly distributed kingfisher species in the world, <em>Todiramphus chloris</em> is recognised by its vivid turquoise or blue-green upperparts and clean white or buff underparts, with a distinctive white collar encircling the neck — a feature that gives the species its common name. The species occupies a remarkably diverse range of habitats, including mangroves, coastal forests, open woodland, and cultivated areas, reflecting considerable ecological adaptability. It is reported to occur in Norway according to available range data. <em>Todiramphus chloris</em> is a sit-and-wait predator, typically perching conspicuously before diving to capture prey such as insects, small reptiles, crustaceans, and fish. Detailed biological traits including typical lifespan, body length, and weight are poorly documented across the full range of subspecies in available literature. The species 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.
