What coyotes do for us
It has been established in bigger cities, like Chicago, that decreases in local predators result in more pest complaints. Coyotes prey upon mice and other rodents that pose a direct threat to your home, and this makes them a useful ally. Also, they keep raccoon and opossum populations in check, which means that the songbirds you love to hear will be safe.
Established packs with an alpha male and female act as guardians for your community. These family packs are directed by the alphas who teach pups how to hunt, what to hunt and where to hunt, which is anywhere but your community! These territorial packs prevent transient coyotes from digging up garbage, preying on pets and posing a problem to your community.
It has been proven that indiscriminate killing of coyotes results in compensatory reproduction and eventual population increase. This occurs through unregulated mating after the extermination of alpha pairs.
With a rapid decrease in predator population comes a concomitant increase in prey animals: rabbits, deer and the like. These prey animals feed on the same forage as rancher's cattle, thus increasing competition for resources. This directly conflicts the interest of ranchers, considering that fewer than 0.5 percent of cattle losses are attributed to predation.
