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.
The first egg hatches after 31 to 36 days of incubation. The eggs hatch successively; although the average interval between egg-laying is 3 days, the young tend to hatch no more than a day or two apart. [19] Like all owls that nest in the open, the downy young are often a mottled grey with some white and buff, which provides camouflage. [8]
Clutch size refers to the number of eggs laid in a single brood by a nesting pair of birds. The numbers laid by a particular species in a given location are usually well defined by evolutionary trade-offs with many factors involved, including resource availability and energetic constraints.
After finding an injured Snowy Owl in Northern Michigan, Jerry Taylor, 15, of South Bend brought it home to nurse it back to health. Headlines in History 1954: Snowy Owl eats Potawatomi Park Zoo's ...
Northern saw-whet owls lay about four or six white-colored eggs in natural tree cavities or woodpecker holes. Males will often sing from a nest site [20] and cache food in nest sites in order to attract a female. [15] The father does the hunting while the mother watches and sits on her eggs.
Barrett said the last substantial sighting came in 2022, noting this year’s visit is part of a snowy owl irruption — an unpredictable migration pattern resulting from a successful breeding season.
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. [18] Normal clutch size is two eggs but may reach four on rare occasions. The female sits on the eggs and cares for the young, while the male provides food for them.
