Summer Diet of the Mexican Gray Wolf (Canis Lupus Baileyi) (Notes) (Report‪)‬

The Mexican gray wolf (Canis lupus baileyi; hereafter Mexican wolf) is the smallest (Hall and Kelson, 1959), most genetically distinct (Wayne et al., 1992; Garcia-Moreno et al., 1996), and most endangered (McBride, 1980; Brown, 1983; Ginsberg and Macdonald, 1990) subspecies of gray wolf (C. lupus) in North America. The Mexican wolf was extirpated from its range in Arizona and New Mexico by the 1970s (Brown, 1983). In May 1976, the Mexican wolf was listed as endangered under the Endangered Species Act. In 1998, the United States Fish and Wildlife Service began a translocation program to establish a nonessential, experimental population of Mexican wolves in the Blue Range Wolf Recovery Area (United States Fish and Wildlife Service, in litt.). One measure of success of the translocation is the ability of Mexican wolves to capture native prey.
