Northern Saw-whet Owls range from coastal Alaska, through southern Canada, the Great Lakes states, New England, and western United States to the central highlands of Mexico.
The population appears to be stable.
These nocturnal owls prey mostly on small rodents but will eat small birds while migrating at night and some insects. They hunt from a low perch at forest edges or clearings.
They nest in natural tree cavities, woodpecker holes, and man-made nest boxes. The female lays 4-7 eggs and the male brings her food while she incubates them for 27-29 days. The young fledge in 4-5 weeks and may be able to reproduce in their first year.
