Collared Kingfisher

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.
