Northern Hawk Owls are distributed across Alaska, Canada, and Eurasia. In winter, they may travel to southern Canada and the northern United States in search of food.
The population appears to be stable.
They feed mostly on voles and other small mammals and birds, hunting from an exposed perch. They swoop down on prey or hover above it before dropping down to catch it. They also fly low over the ground in search of food.
They nest in hollows in stumps and trees, as well as the abandoned nests of hawks and crows. The female lays 3-10 or more eggs, depending on the size of the prey population. The eggs are incubated for 25-28 days. The young fledge when they are 3-1/2 to 5 weeks old and are independent at 11 weeks.
