About the Great Gray Owl

The great grey owl (Strix nebulosa) (also great gray owl in American English) is a true owl, and is the world's largest species of owl by length. It is distributed across the Northern Hemisphere and is the only species in the genus Strix found in both Eastern and Western Hemispheres.

Adults have large, rounded heads with grey faces and yellow eyes with darker circles around them. The underparts are light with dark streaks; the upper parts are grey with pale bars. This owl does not have ear tufts and has the largest facial disc of any raptor. A white collar or "bow-tie" is just below the beak. The long tail tapers to a rounded end.

In length, the great grey owl is believed to exceed the Eurasian eagle-owl and Blakiston's fish owl as the world's largest owl.

Much of its size is deceptive, since this species' fluffy feathers, large head, and the longest tail of any extant owl obscure a body lighter than that of most other large owls. The length ranges from 61 to 84 cm (24 to 33 in), averaging 72 cm (28 in) for females and 67 cm (26 in) for males. The wingspan can... Wikipedia →
