The snowy owl (Bubo scandiacus), [4] also known as the polar owl, the white owl and the Arctic owl, [5] is a large, white owl of the true owl family. [6] Snowy owls are native to the Arctic regions of both North America and the Palearctic, breeding mostly on the tundra. [2]
Owls are divided into two families: the true (or typical) owl family, Strigidae, and the barn owl and bay owl family, Tytonidae. [2] Owls hunt mostly small mammals, insects, and other birds, although a few species specialize in hunting fish. They are found in all regions of the Earth except the polar ice caps and some remote islands.
They are similar in size to the American robin (78.5 g). [13] Northern saw-whet owls do not exhibit sexual dimorphism in their plumage, so are often sexed by size dimorphism—females are larger than males. Females on average weigh 100 g and males on average weigh 75 g. [15] Northern saw-whet owls have porphyrin pigments in their flight ...

The species does not normally breed every year, with average breeding probability being 62%. Young owls may start breeding at an the of one year but two years or older is more common.

[123] [116] The mean size of prey taken is seldom estimated in the barred owls' eastern range, although one study estimated mean size of prey in the general east was 33.5 g (1.18 oz). [136] Many more studies have estimated mean prey masses in westerly areas of sympatry with spotted owls to understand how their diets may conflict. [ 123 ]
