Here in the Greater Yellowstone area we have a good population of a variety of owls. Owls being mostly nocturnal are seldom seen by Yellowstone visitors, but they surely are a treat for the photographers who succeed at seeking them out.

The most common is the Great Horned Owl which is one of the most widespread owls in North America. Great Horned Owls can vary in color from reddish brown to a grey or black and white. The underside is a light grey with dark bars and a white band of feathers on the upper breast. They have large, staring yellow-orange eyes, bordered in most races by an orange-buff facial disc. The name is derived from tufts of feathers that appear to be "horns" Great Horned Owls hunt by perching on snags and poles and watching for prey, or by gliding slowly above the ground. From high perches they dive down to the ground with wings folded, before snatching prey. Their prey is usually killed instantly when grasped by its large talons.
