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.
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 ...
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]
Eggs are laid at two-day intervals and incubation begins after laying of the first egg. Eggs vary in size in synch with their ultimate body size, ranging from an average of 36.3 mm × 30.2 mm (1 + 7 ⁄ 16 in × 1 + 3 ⁄ 16 in) in the Northern Rockies to 33.9 mm × 29.2 mm (1 + 5 ⁄ 16 in × 1 + 1 ⁄ 8 in) in south Texas.

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.
A clutch of 3 to 5 eggs is laid (occasionally 2 to 8). The eggs are broadly elliptical, white and without gloss; they measure about 35.5 by 29.5 mm (1.40 by 1.16 in). They are incubated by the female who sometimes starts sitting after the first egg is laid. While she is incubating the eggs, the male brings food for her.
