Great Gray Owl

The Great Grey Owl (Strix nebulosa) (also great gray owl in American English) is a very large owl, documented as the world's largest species of owl by length. The only species of Strix to be found in both the Eastern and Western Hemispheres, it is widespread throughout the Northern Hemisphere. In some areas, it is also called Phantom of the North, cinereous owl, spectral owl, Lapland owl, spruce owl, bearded owl, and sooty owl.

Adults have broad, rounded heads, grey faces, and yellow eyes that have darker circles surrounding them. The upper parts are grey with pale bars, whereas the underparts are light with dark streaks. This owl has the largest face disc of any raptor and no ear tufts. Just below the beak, there is a white collar or "bow-tie". The lengthy tail gradually rounds off.
