The snowy owl is a large, powerful owl of the high Arctic tundra, with regal white feathers and brown markings suited for camouflage during northern winters. During the winter, the snowy owl irregularly shows up in windswept fields and dunes. It is the largest of all North American owls. During the summer it is often nomadic, nesting and inhabiting areas where there are large populations of the small rodents called lemmings. Remote North American breeding areas are safe from the effects of human disturbance, though the effects of climate change are beginning to affect their habitat. Snowy owl populations have declined in parts of the breeding range in northern Europe. When their favorite food source, the lemming, is scarce, it takes a wide variety of prey, including birds as big as geese. During some winters, large numbers of Snowy Owls appear south of the Canadian border. Their appearance in towns and cities invariably attract many observers, photographers, and media attention. “Snowy Owl On A Winter Night” is a Spadecaller digital painting and photo composite.
