Spotted owl

The spotted owl (''Strix occidentalis'') is a species of true owl. It is a resident species of old-growth forests in western North America, where it nests in tree holes, old bird of prey nests, or rock crevices. Nests can be between high and usually contain two eggs (though some will contain as many as four). It is a nocturnal owl, which feeds on small mammals and birds. Three subspecies are recognized, ranging in distribution from British Columbia to Mexico. The spotted owl is under pressure from habitat destruction throughout its range, and is currently classified as near threatened.
==Description==
The spotted owl has an average length of , wingspan of , and weight of . Its eggs are a little over long, and are white and smooth with a slightly grainy texture. The spotted owl is similar in appearance to the barred owl but has cross-shaped markings on the underparts, whereas the barred owl is alternately barred on the breast and streaked on the belly. Barred owls are larger and grayer than spotted owls. In recent years the California and northern subspecies of spotted owl have been displaced by barred owls, which are more aggressive, have a broader diet and occur in more varied habitats. Though the two species may hybridize in areas where displacement is occurring, they are genetically quite distinct.〔
