Field Notes

Description:

"Adults have a big, rounded head with a grey face 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."

"One of the World's largest Owls, the Great Gray Owl is dark grey overall interspersed with bars and flecks of light grey and white. When perched, they appear very bulky because of their dense, fluffy plumage, long wings extending past the body, a relatively long tail, and a large head. The size of the head, and the prominent facial disk make the yellow eyes appear small. A noticeable white "moustache" strip is under the facial disk, broken by a black "bow-tie". The feet are heavily feathered and remain hidden from view."

Habitat:

"Great Gray Owls inhabit a range of forested habitats. In far north America, they frequent stunted coniferous forests along the edge of the Arctic treeline, through spruce and tamarack muskeg forests further south. In the Sierra Nevada Mountains they breed in mixed conifer and red fir forests. Nesting habitat usually includes copses or islands of aspens within pure stands of conifers. Most foraging is done in open areas such as swamps, bogs, and forest clearings where there are scattered trees and shrubs that can be used as perches. During migration they may be found in estuaries, mountain meadows, and along farm fields. They are found from Alaska across Canada, down the Northern Rocky Mountains, and northern Minnesota. They are also found in northern Europe and Asia."
