What are the habitat requirements of the primary Northern Spotted Owl prey?
They prefer old-growth forests, particularly Douglas fir forests, that typically take 150 to 200 years to mature. These types of forests have high canopy layers, snags (standing dead trees), and open spaces for flying underneath and between trees.
What is the spotted owl habitat like?
coniferous forests
Habitat: Spotted owls live in mature coniferous forests with dense canopy cover at low and moderate elevations. The fragmentation of conifer forests has lead to increased occupation by Great Horned Owls and, in the past 20-30 years, the invasion of Barred Owls.
Do spotted owls eat insects?
California spotted owls eat a variety of mammals, birds and insects, but usually select a few key species.

Where can you see spotted owls?
California spotted owls can be found in four general forest types in Southern California: riparian-hardwood forest, live oak/bigcone Douglas-fir, mixed conifer forest, and redwood/California laurel forest.
How rare is the Spotted Owl?
There are fewer than 6 individuals left in British Columbia, Canada; 1,200 pairs in Oregon, 560 pairs in Northern California, and 500 pairs in Washington. Washington alone has lost over 90 percent of its old growth forest due to logging which has caused a 40-90 percent decline of the Northern Spotted Owl population.
Are northern spotted owls carnivores?
Spotted owls are carnivores and most of their diet includes flying squirrels, woodrats, deer mice, pocket gophers, voles, snowshoe hares, and several species of squirrels.
How can we help the northern spotted owl?
Reserve areas and critical habitat have been designated to help recover owl populations, and monitoring reports indicate that habitat restoration efforts on public lands are working.
Do owls drink water?
When fat from prey is metabolized, or processed to release its energy, water is produced. For every gram of fat that is metabolized, the bird gets 0.04 ounces (1.1 grams) of water as well as energy. Nestlings are not provided with water for drinking. Adult owls will drink water on occasion when they are bathing.

What are the threats to the spotted owl?
Impacts from habitat loss of mature forest are now worsened by the effects of competition with barred owls for prey and habitat. As the population declines and becomes even smaller, other threat factors may become more relevant. Spotted owls are about 17 inches in length.
How often do northern spotted owls breed?
