Boreal Owl, Birds of the United States, Thomas Nuttall
Small. Mostly pale facial disks with dark border. Dark brown upperparts with large white spots. Pale underparts with large, dark irregular streaks. Yellow eyes. The Boreal Owl is most likely to be confused with the smaller Northern Saw-whet Owl but lacks brown in the face, has a pale bill, has a dark border to the face and darker brown upperparts.

As its name indicates this owl is found in northern coniferous and mixed hardwood forests. Distributed circumpolarly it is found in northern Europe (where it is known as Tengmalm's Owl), Northern Asia, Alaska, and Canada. It is most common in spruce or pine woods, although it is regularly found nesting in aspen in Minnesota.

The first report of its nesting in the lower 48 states came from Minnesota in 1978. Since then a breeding population has been found in northeast Minnesota and local populations reported in Idaho, Montana, Wyoming, Colorado and Washington.

While not considered a common resident of the lower 48 states, ongoing research may cause a reassessment of this birds status in the near future. Two projects are currently being conducted in Minnesota to determine the population status of this owl.
The Boreal Owl is a cavity nester which will also use nest boxes, particularly in Europe. The male sings near a cavity to attract a female. The female does most of incubation while the male feeds her.

Lays three to six eggs which hatch after about four weeks incubation and young leave the nest in about another four or five weeks.

Night hunter of small mammals and lesser quantities of birds. Population densities and migrations of the Boreal Owl can be tied to rodent populations.
