Cactus Ferruginous Pygmy Owl, by Mike Wrigley, USFWSThis small owl with a wingspan of about 15 inches is common and widespread in the American tropics. It enters the U.S. only in southern Texas and Arizona, where it is uncommon. Unlike many owls it is active by day, preying on insects, birds, rodents and lizards. It has a large rounded head, yellow eyes and a crown flecked with white. The underside is rusty brown, and both sexes have the same appearance. United States range includes southern Arizona and Texas, seems to be year-round resident throughout its range.
