Inhabits dense coniferous forests, groves and tree stands in farms
and towns from the middle U.S. north to Canada and Alaska and in the southwest mountainous
regions as far Mexico in the winter. Like its cousin, the Boreal Owl, it inhabits the
northern latitudes around the globe.
Makes a nest of loose chips and
feathers in natural or abandoned tree cavities, rock clefts, sometimes
in abandoned squirrel, crow or heron nests, in building towers and in
bird houses which have been used for hundreds of years for rodent control.
Night hunter for mice and insects. Its note resembles the filing of a saw.
