Great grey owls hunt using their vision and hearing, at night and around dusk or dawn, though they may hunt in daylight if they are feeding their young. They are one of the only owl species to engage in a behavior known as “snow plunging”, in which they can dive up to two feet into snow to capture prey. They are able to locate animals underneath snow cover due to their excellent hearing.
Their prey mostly consists of small rodents, including lemmings, voles, gophers, squirrels, hares, moles, shrews and weasels. Few animals are predators of the great grey owl. While some animals like bears may prey on the young owls, the only true predator if the adult great grey owl is the eagle owl.
The great grey owl makes no nest of its own, so it relies on abandoned nests of other large birds, or a large cavity in a tree. It usually lays four eggs per clutch, each about 2 inches in length. After about a month, the eggs hatch, and the young will begin to practice flying after about three or four weeks by jumping (or falling!) out of the nest. They will have to use their feet and beaks to climb back up. After a couple weeks of this “practice”, they will start to fly on their own.
The great grey owl is largely grey in color with brown, grey and white streaks. It has yellow eyes and a white "X" of feathers between its eyes, as well as a white patch of feathers on its chin arranged in a “bow tie”.
It has a very large facial disc, which is an arrangement of feathers that frames the head and helps enhance the owl’s hearing. It has the largest of these discs of any owl.
While the great horned owl and eagle owl are heavier, they are not as long as the great grey owl, which can grow up to 33 inches in length. Despite its length, it only weighs around three to four pounds, with much of its bulky appearance being composed entirely of feathers. Its wingspan can reach over five feet.
The great grey owl is found mostly in colder habitats in the far north, in North America, Europe and Asia. It is the only species in its genus found in both the Eastern and Western Hemispheres. It prefers dense forests with nearby open areas.
The great grey owl is the provincial bird of Manitoba, Canada.
The great grey owl is known to be very elusive and hard to spot in the wild. Unlike other birds, which often fly away if a human draws near, great grey owls often remain still and are easily overlooked by passersby.
The great grey owl is a species of Least Concern. The biggest threat to this species is logging from the forests that make up its habitat. Pesticides meant to control rodents can also harm great grey owls. In some areas, nesting platforms have been set up to help owls who are unable to find suitable trees to nest in.
