The snowy owl (Bubo Scandiacus) is also known as the Arctic owl or the great white owl. It is primarily found within the Arctic Circle with a across Canada, Greenland, Europe and Asia. The snowy owl is the official bird of Quebec in the North-east of Canada. Unlike many other owls, the snowy owl is not nocturnal. With almost constant daylight during their breeding and nesting periods in the Arctic, they spend summers far north of the Arctic Circle hunting lemmings, ptarmigan, and other prey in 24-hour daylight. Male Snowy Owls are barred with dark brown when they’re young and get whiter as they get older. Females keep some dark markings throughout their lives. Although the darkest males and the palest females are nearly alike in colour, the whitest birds – including the ones that played Harry Potter’s Hedwig – are always males and the most heavily barred ones are always females.
