The Research Brief is a short take on interesting academic work.
THE BIG IDEA: Coyotes are poised to expand their range to a new continent. The North American canine native has now reached the Darién Gap – a dense wilderness on the border of Colombia and Panama, at the very doorstep of South America. If the coyote succeeds, it would be a new chapter in an amazing evolutionary story that's played out over the past half century.

Wildlife advocacy groups cheered when the Trump administration reversed its decision to approve the use of deadly predator traps known as "cyanide bombs" in August. But now the administration has reversed course again. The Environmental Protection Agency (EPA) published an interim decision Thursday and approved their use with added safety measures.

Coyotes in urban spaces have become the new normal. There is now a large, and growing, population of coyotes in San Francisco. Residents in Los Angeles, Phoenix and Denver—among many other western cities—have long lived alongside coyotes.

The Animal Legal Defense Fund filed a complaint last week on behalf of a Wyoming resident in an attempt to stop an upcoming coyote-killing contest. The "Wyoming Best of the Best" involves teams of hunters vying to kill as many coyotes as possible from sunup to sundown.
Non-hunting participants place bets on the teams they think will kill the most coyotes. The complaint alleges the event constitutes a nuisance in the form of illegal gambling, since participants wager money and the outcome is based predominantly on chance. Illegal gambling is a violation of the state nuisance statute, designed to prevent activities that put the moral integrity and safety of the community at risk.
The Rock Springs event is scheduled for this coming weekend, Feb. 3 – 4. The rules encourage people of all ages and experience to enter, including children.
Wyoming Best of the Best involves betting opportunities for most coyotes killed, biggest coyote killed, littlest coyote killed, a rifle raffle and a Calcutta—a form of betting pool where participants pick winners and the pool of funds is distributed according to a prearranged scale of percentages, to those who selected winners. Hunting participants wager $50 per person for the chance to win cash prizes and advance to the state championship for killing the most coyotes. Teams may also wager an extra $20 per team to enter the "Big Dog/Little Dog" contests, for the chance to win extra cash prizes for killing the biggest and/or littlest coyote.

The killing contest is not regulated by any government agency, hunting licenses are not required in Wyoming to kill coyotes and there is no limit on the number of coyotes a hunter may slaughter. The plaintiff worries the influx of hunters, whose goal is to win cash prizes for the indiscriminate and uncontrolled killing of coyotes, will negatively impact Sweetwater County's wildlife.
The contest also causes a serious disruption in the ecosystem leading to an unbalanced and unhealthy natural system. When coyote populations are disrupted by lethal means, younger pups have no adults to help them acquire food. This in turn causes many pups to prey on sheep and livestock. The disruption can also affect smaller predator populations by destabilizing entire ecosystems.
"Killing contests are simply blood sports," said Animal Legal Defense Fund Executive Director Stephen Wells. "They are completely inconsistent with appropriate conservation goals or effective wildlife management. Coyotes are essential members of healthy ecosystems, not targets to be killed for 'fun.'"
