Abstract

To provide information on comparative habitat use, we studied radiotagged Mexican spotted owls (Strix occidentalis lucida: n = 13) and great horned owls (Bubo virginianus: n = 4) in northern Arizona. Home-range size (95% adaptive kernel estimate) did not differ significantly between species during either the breeding or nonbreeding season. Home ranges overlapped considerably between species, but overlap in use of individual stands was limited. Relative area of 4 canopy-cover classes (
