Both species primarily preyed on a few groups of. reproductive output of coexisting Kestrels and Long-eared Owls. Oecologia 74 The book begins with a description of habitats and vegetation types in the high country, and which raptors are. Barred owls are perceived to be forcing spotted owls out of their habitats and causing local extinctions, but one current hypothesis (to be tested by this project) is that spotted owls may compete better with barred owls in dry forests of the eastern Cascade Mountains than in the more mesic and wet west-side and coast range Overview Overview.
