Dickerman and Johnson (2008) described subspecies Bubo virginianus pinorum of the Great Horned Owl, designating a type specimen from the Sandia Mountains of north-central New Mexico and outlining the range as “plains of the Snake River of Idaho, south ... at increasing elevations, to Arizona and New Mexico.” Bubo v. pinorum is darker dorsally and more heavily barred ventrally than the pale B. v. pallescens of the desert Southwest or B. v. subarcticus of the Canadian prairie parklands but paler and more lightly barred than in B. v. lagophonus or B. v. sturatus to the northwest or in B. v. pacificus of coastal California. Here I trace the distribution of B. v. pinorum further, extending it north and west to central and northern Washington.
