Range and Habitat
Western Screech-Owl: Common resident in much of the western U.S., Canada, and Mexico in a variety of habitats. Preferred habitats include open woods, especially oak, mixed pine/oak, and sycamore.
The Western Screech-Owl is a relatively small owl, and is a close relative to the European Scops Owl and the North American Eastern Screech Owl. Breeding habitats for this species include open deciduous and mixed woodlands throughout the western portion of North America. Nests are insulated cavities in trees or cacti; these are sometimes abandoned woodpecker holes. This bird does not migrate in winter months, and is a permanent resident throughout its range. Diets usually consist of small mammals and invertebrates found on the forest floor. The conservation rating for the Western Screech-Owl is Least Concern.
The Western Screech Owl was first described in 1867. Common names include Little Horned Owl, Dusk Owl, Ghost Owl, Mouse Owl, Cat Owl, Little Cat Owl, Puget Sound Screech Owl, Washington Screech Owl, and Coastal Screech Owl.
At one time, the Western and Eastern Screech Owl were considered to be one species, but they have since been split into two separate species.
When threatened, they stretch their body and tighten their feathers in order to look like a branch stub. They become motionless if disturbed at roost, and can sometimes be caught by hand in this state.
A group of owls has many collective nouns, including a "bazaar", "glaring", "parliament", "stooping", and "wisdom" of owls.
