I'd say that coyotes in an urban setting are a different story than in the desert or in the river bottoms. These coyotes were no longer very afraid of dogs or humans, and their natural prey was long gone. There were lots of accounts of folks finding bits and pieces of their missing pets and packs of 3 or 4 coyotes circling and intimidating kids.
Very true. Coyotes have to eat and they're carnivores. I used to find jackrabbit parts everywhere. People taking over and displacing rabbits, squirrels etc only leaves cats, small dogs and kids.
