Other American Horned Owls
Of the several geographical races the Western Horned Owl (B. v. pallescens) is similar but much lighter in color, the buff markings being largely replaced by gray or white and the darker ones less dusky and of less extent; it is found in the western United States except on the northwest coast, where it is replaced by the Dusky Horned Owl (B. v. saturatus), which is an extremely dark-colored race, the prevailing color being fuscous or dusky.
The Arctic Horned Owl (B. v. subarcticus) is still lighter colored, the prevailing aspect being white and the dark markings being very much reduced in extent. Lower California is the home of a small race known as the Dwarf Horned Owl (B. v. elachistus), which Brewster describes as being similar to the dusky form (saturatus), but very much smaller. It is common everywhere from the coast to the top of the highest mountains.
