摘要

California supports a declining population of resident and migratory Western Burrowing Owls, Athene cuniculariahypugaea, which occur in grasslands throughout the State. Primary causes of population declines in California are conversion of grassland habitats to agriculture or urban land uses and eradication of fossorial mammals, such as the California ground squirrel (Spermophilus beecheyi; Haug et al. 1993). The Burrowing Owl, identified as a species of special concern by the California Department ofFish and Game, appropriates burrows made by other animals. Burrowing Owls usually do not excavate their own burrows. Burrowing Owls also require open grassland fields with a sufficient food supply for foraging habitat, low vegetative cover to allow owlsto watch for predators, and adequate roosting sites (Zarn 1974). The owl is protected under the Migratory Bird treaty Act of 1918 (16 U.S.C. 703-712; Ch. 128; July 13,1918;40 Stat. 7 5 5, as amended), which prohibits the destruction of owls or their nests. California Fish and Game Code (sections 3503,3503.5,3513,3800-3806) also protects these owls, their nests, eggs, and young (LawTech Publishing 2004). When economic development or other land conversion is planned where these owls occur, the CaliforniaDepartment ofFish and Game often suggests mitigation for the destruction of burrows during development projects, or similar activities.
