  The Snowy Owl was first classified in 1758 by Carolus Linnaeus, the Swedish Swedish naturalist
who developed binomial nomenclature to classify and organise plants and animals
. The name "scandiacas" is a Latinised word referring to Scandinavia,
as the Owl was first observed in the northern parts of Europe.
Some other names for the Snowy Owl are Snow Owl, Arctic Owl, Great White Owl, Ghost Owl,
Ermine Owl, Tundra Ghost, Ookpik, Scandinavian Nightbird, White Terror of the North,
and Highland Tundra Owl.

Snowy Owls are active during the daytime, from dawn to dusk.
They have a direct, strong, and steady flight with deliberate, powerful downstrokes
and quick upstrokes.
They make short flights, close to the ground, from perch to perch
, and usually perches on the ground or a low post.

During hot weather, they can thermoregulate by panting and spreading their wings.
Snowy Owls are very aggressive when defending their nest.

During the breeding season males have a loud, booming "hoo, hoo"
given as a territorial advertisement or mating call.

Most hunting is done in the "sit and wait" style.
These Owls are highly diurnal, although they may hunt at night as well.
Prey are captured on the ground, in the air, or snatched off the surface of water bodies.
