Abstract:

The average maximum distance radio-ragged adult Great Gray Owls (Strix nebulosa) traveled from their nest sites was 13.4 km. Average size or home range was 67.3 km². Maximum dispersal distance of juvenile Great Gray Owls from natal sites averaged 18.3 km, and home range averaged 139 km². Three juvenile owls had an average home range or 167 km² their first year of life and 13 km² their second year of life. Over 90% of radio-tagged owls dispersed to areas with less snow during the winter.
