Formerly in the genus Otus, the Pacific Screech-Owl can be found within its range in dry woodland, semi-open country, second-growth and lakeside fields. Even though this species has a relatively small contiguous range, there are three subspecies of Pacific Screech-Owl that are recognized. Strictly nocturnal, this species is rarely seen or heard during the day. A small owl, the Pacific Screech-Owl feeds mainly on insects, including beetles, katydids, moths, and scorpions, but it has also been know to hunt small rodents. Cavity nesters, the Pacific Screech-Owl often takes over old woodpecker cavities for their nests.
