A Reference for North and Central American Owls
The Spotted Owl is usually sedentary and occupies only one territory most of its life. Its sedentary nature, narrow habitat requirements and vocal habits make it very vulnerable to people. This is probably the most studied bird in the world. It is highly debated while its numbers continue to decline range-wide. Of the three races of Spotted Owl (Northern, California, and Mexican Spotted Owl), only the California Spotted Owl has not been protected by the Endangered Species Act. After being sued, the U.S. Fish and Wildlife Service settled on completing its review of the California Spotted Owl by 2019. Here you will find video, photos, recordings, information, discussion, and a brief field notes section to help identify and enjoy this beautiful owl.
