The Western ScreechOwl is a very common resident in much of the Western U.S., Canada and Mexico and is often the most abundant night predator in its range.

Separation in the field, of the ScreechOwls, is actually only feasible by voice. The Western ScreechOwl can be distinguished with his primary "bouncingball" (territorial) call. This is a common owl in the west. The sexes are alike in appearance although male and female can be distinguished by voice. The ear tufts may or may not be visible in the field. Color varies but most commonly they are gray to brownish (a rare red form is also in costal British Columbia and Alaska). The bill is almost always black and the eyes are yellow. Length is 8 1/2" (about the size of a Redwinged Blackbird). A nocturnal owl.
