COYOTE ATTACKS: AN INCREASING SUBURBAN PROBLEM
Introduction Coyote (Canis latrans) attacks on humans, once thought to be rare, have increased in frequency over the past decade. In expanding suburban areas such as those found in several counties in Southern California, residential developments are often near steep, brushy wildland areas. Coyotes inhabiting such wildlands are drawn into suburban landscaped environments that can support an abundance of rodents and rabbits, and where they can utilize water sources, pet food, household refuse, and even house cats and small dogs as prey.
Our observations indicate that in the absence of harassment by residents, coyotes can lose their fear of people and come to associate humans with this safe, resource-rich environment. This problem is exacerbated by people who intentionally feed coyotes. In such situations, some coyotes have begun to act aggressively toward humans, chasing joggers and bicyclists, confronting people walking their dogs, and stalking small children.
We queried representatives of various federal, state, county, and city agencies as well as private wildlife control companies about coyote attacks on humans occurring in Southern California during the past three decades, giving particular attention to localities where such attacks previously had been verified (see Howell 1982, Baker and Timm 1998). From the information gathered, we now list 89 coyote attacks in California (incidents when one or more coyotes made physical contact with a child or adult, or attacked a pet while in close proximity to its owner) (Table 1). In 56 of these attacks, one or more persons suffered an injury (Figure 1). In 77 additional encounters (not listed), coyotes stalked children, chased individuals, or aggressively threatened adults. In 35 incidents (not all listed), where coyotes stalked or attacked small children, the possibility of serious or fatal injury seems likely if the child had not been rescued. Because no single agency maintains data on such attacks, and some agencies and organizations are reluctant to discuss such incidents, we recognize that we do not have data on all attacks that have occurred.
We also questioned representatives of agencies and private firms about the results of their corrective and preventive actions taken in relation to coyote attacks. We summarize and discuss this information as a contribution toward improved strategies to deal with this wildlife-human conflict....
