The three little plush Great Grey Owl stuffed animals on the right are made by Wild Republic and one is part of their Audubon Bird series, which hoots just like a Great Grey Owl when squeezed. The Grey Owl on the left is Ollie and is made by Bearington.
The Great Gray Owl (Strix nebulosa) is the largest owl in North America and one of the largest owls in the world (from 24 to 33 inches). There are an estimated 50,000 Great Grays in North America. Inhabiting coniferous forests of the Northern Hemisphere, they are not migratory but will leave their territories if their food supply runs short. They prefer dense forests (pine, spruce, poplar and larch) with adjacent meadows. Having evolved in the northern latitudes, where there are long periods of light, they hunt equally well both day and night. The diet consists of voles and other small rodents and birds. Their excellent hearing allows them to detect the movement of rodents in their tunnels. Rather than building their own nests, they use the old nests of hawks and crows to lay their white eggs, numbering from two to six (occasionally nine). The eggs are laid from mid-March to June and take about 30 days to hatch. At about two months, the owlets take their first flights. These large dusky gray birds are striped lengthwise on the underparts. The large head (almost 20 inches in circumference) is round without ear tufts. Yellow eyes are edged on the inside with black, then that is edged with a white, comma-shaped streak. The large facial disc has a dark ruff encircling the face. Within that there are concentric circles of gray-brown on white. There is a noticeable black spot on the chin. The tail (about 12 inches) is very long for an owl. The voice is a deep booming whoo-hoo-hoo.
