One of the most elusive and mysterious looking owls is the great gray. Despite being the largest type of owl in North America, the great gray is one of the most difficult to find.

Range and Habitat

To find these large birds of prey, head to the western states or far north near the Canadian border.

The species ranges across the forests of the West, in the mountains from California to Wyoming, as well as the boreal forest of Alaska and the western two-thirds of Canada. The more-than-2-foot-tall bird is perfectly camouflaged to reside in dense conifer forests.

Great gray owls rarely venture south, except when extreme cold forces them to seek food. Irruptions of this species only happen under the harshest of conditions.

Nesting Habits

Rather than build their own nests, the giants take over structures built by squirrels, ravens or other raptors. Great grays will often return to the same nest year after year.

Great gray owls avoid populated areas, so they’re difficult to spot. But when caring for young, they’re more likely to venture out in daylight to hunt rodents.

Heavy snow is no match for these owls as they hunt for food.

Great gray owls move out to open bogs, muskegs and meadows to hunt their small mammal prey. This owl is one of the mightiest and can plunge into deep snow to snag a vole snack. During winter, great gray owls consume up to seven rodents a day.

If you are lucky enough to see a great gray, resist the temptation to play calls or to feed it—both practices are unsafe for the owl. Instead, give the bird plenty of space. The memory will remain with you for forever.


The Minnesota DNR reports that the great gray owl vocalizes with deep sounding, repetitive hoots.

Birders visit Sax-Zim Bog in Minnesota during winter to spot these large owls.

From December to March, Sax-Zim Bog in northern Minnesota becomes home to uncommon boreal birds from Canada.

“On a cold winter’s day in Sax-Zim Bog, we spotted this great gray owl (above) hunting along a gravel road. It is amazing how good their hearing is. He kept turning his head from side to side listening for the sounds of a vole moving beneath the snow. After about 10 minutes or so, he dove towards the ground and pounced on his meal. The snow was about a foot deep, but that didn’t keep him from a successful hunt. I was using a Canon R5 and a 600 f4 to photograph him,” says reader Kevin Oneill.
