Almost strictly nocturnal, the Western screech-owl hunts discreetly at night and roosts during the day in dense woodlands, its perfectly streaked plumage allows it to pass as tree bark. These habits make it difficult to see, and it is more common than many are aware.
It is a small owl with yellow eyes and feathered ear tufts. It exhibits geographic variation in plumage color and pattern: both gray morphs and brown morphs occur in the Pacific Northwest. Sexes are alike.
The Western screech-owl is a fairly common year-round resident in lower-elevation woodlands throughout Oregon. It is usually found below 3,000 feet in western Oregon, but has occurred at least to 4,100 feet in the west Cascades.
