Interesting Facts about the Snowy Owl

  • Unlike most other owls, the Snowy Owl hunts mainly during the daytime.
  • The Snowy Owl's breeding habitat is open tundra, from just above the treeline and continuing to higher elevations.
  • Depending on the abundance of food, many of these owls remain on their breeding territory throughout the year. However, some of them migrate further south and are seen in the very northern parts of the United States, including northern New England.
  • In some years, a much larger number of Snowy Owls migrate southward during the winter. The reason for this is uncertain, but it is thought that this may be due to a temporary decrease in the lemming population, the main food source for this bird in the Arctic.
  • This large owl remains mostly silent except during the breeding season, when the male makes a loud, booming hoot that can be heard for quite a distance. The Snowy Owl also makes barking and hissing sounds.
  • The Snowy Owl does not mate for life but instead remains monogamous for only one breeding season.
