Snowy Owl (Bubo Scandiacus)

October 12, 2012 by  

Snowy Owl (Bubo Scandiacus), The Snowy Owl (Bubo scandiacus) is a large owl of the typical owl family Strigidae. The Snowy Owl was first classified in 1758 by Carolus Linnaeus, the Swedish naturalist who developed binomial nomenclature to classify and organize plants and animals.

Until recently, it was regarded as the sole member of a distinct genus, as Nyctea scandiaca, but mtDNA cytochrome b sequence data (Olsen et al. 2002) shows that it is very closely related to the horned owls in the genus Bubo. The Snowy Owl is the official bird of Quebec.

This yellow-eyed, black-beaked white bird is easily recognizable. It is 52-71 centimetres (20-28 in) long, with a 125-150 centimetres (49-59 in) wingspan. Also, these birds can weigh anywhere from 1.6 to 3 kilograms (3.5 to 6.6 lb). It is one of the largest species of owl and, in North America, is on average the heaviest owl species. The adult male is virtually pure white, but females and young birds have some dark scalloping; the young are heavily barred, and dark spotting may even predominate. Its thick plumage, heavily feathered taloned feet, and colouration render the Snowy Owl well-adapted for life north of the Arctic Circle.

Snowy Owl calls are varied, but the alarm call is a barking, almost quacking krek-krek; the female also has a softer mewling pyee-pyee or prek-prek. The song is a deep repeated gawh. They may also clap their beak in response to threats or annoyances. While called clapping, it is believed this sound may actually be a clicking of the tongue, not the beak.
