Taxonomy
Bubo vs. Nyctea
Recently updated authorities (Clements 6th edition, 2007; IOC 1.6, 2008) have reassigned Snowy Owl (scandiacus/a) to the genus Bubo because DNA results place Snowy Owl among branches containing Bubo owls. However, Howard & Moore (2003) and Sibley & Monroe (1996) retain this species in Nyctea, and the Opus awaits further clarification.
Habitat
Marshes, beaches, and other open areas, often seen on airport runways
Behaviour
Diet
In breeding season, predominantly lemmings. Breeding success often depends on the abundance of these rodents. An accomplished hunter. Known to take a wide variety of birds, including ptarmigan, shorebirds, songbirds, and waterfowl, which can even be captured in flight after a pursuit. Another favourite is rabbits and particularly snowshoe hare. Reported to even snag fish from water.
In Culture
The Snowy owl was used in the Harry Potter series as the protagonist's pet and messenger. Snowies can be found in several books and movies, and many birders and non-birders alike have been captivated by their beautiful appearance.
