Mexican spotted owls inhabit remote canyons and old-growth Douglas fir forests of the four corners states, hundreds of miles from its relatives the northern (Strix occidentalis caurina) and California spotted (Strix occidentalis occidentalis) owls. This secretive species with distinctive brown eyes has greatly declined because of habitat loss as a result of logging. In 1993 when the U.S. Fish and Wildlife Service listed the Mexican spotted owl as Threatened, it estimated that only around 2,100 owls remained. However, the agency went on to approve Critical Habitat that excluded most of the known owl populations in Arizona and New Mexico. CNE joined Center for Biological Diversity and Diné Citizens Against Ruining our Environment in challenging this decision in court. Our lawsuit was successful, and the Service has been ordered to redefine Critical Habitat for the Mexican spotted owl.
