Eastern Coyotes Flex Muscle
Close human-coyote encounters are not restricted to California. In New York State, wildlife biologist Gordon Batcheller studies coyotes from his post at the state's Department of Environmental Conservation (DEC).
He said coyotes are "becoming habituated to humans and human environments, and adapting their behavior to ours."
From the coyotes' perspective, this human environment "is a 'subsidized environment,' meaning it provides an artificially high amount of foods with an unnatural absence of threats," Batcheller said. "These adaptable animals take quick advantage of these unnatural environments."
At Cornell University in Ithaca, New York, wildlife biologist Paul Curtis and his team are beginning a five-year study of coyote ecology and behavior, funded in part by the state's DEC.
"The goal of the project is to look at changes in both coyote and human behavior that may be leading to more conflicts and complaints," Curtis said.
New York DEC officials estimate that 20,000 to 30,000 coyotes live in the state.
Curtis describes a progression of behavior in so-called problem coyote areas. First, the generally reclusive animals are increasingly spotted in daylight hours. Next, pets begin to vanish from yards and are even snatched off leashes by coyotes.
"That's the last stage before a human attack," Curtis said. "And we're at that stage in New York now." New York wildlife officials hope to head off such conflicts before a serious attack or death occurs.
Most coyotes, even those living near humans, are seldom seen and are reclusive. But dealing with human-adjusted animals is a management challenge.
"It appears to be a learned behavior," Curtis noted. "Certain animals seem more adapted to an urban environment. They catch a few cats and say, Hey there is abundant food here."
Animal control officers are experimenting with ways to reintroduce fear of humans in coyotes that have lost it. Many states have open season on coyote hunting. But the practice is controversial and often impractical in suburban and urban areas, where most problems occur.
Other non-lethal methods, including rubber buckshot and fencing, have met with mixed results.
"If they persist in aggressive behavior, the ultimate solution would probably be to remove problem animals," Curtis said. "Nobody is happy about that."
