USGS Saw-whet Owl Map

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.

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

The Saw-whet Owl Nestbox (same as for Pigmy Owl, Lewis Woodpecker Flicker, and Grackle) has a 7" by 7" floor, 16" inside ceiling, 2 1/2" diameter entrance hole located 14" above the floor and ventilation openings.
