Chicago's Thriving Coyotes - Stanley Gehrt

There are coyotes running wild on the streets of Chicago. Initially when Stanley Gehrt started studying the urban coyotes, he thought there would be a few dozen of them, and that they would easily be deterred from making the city their home. But living close to large numbers of people means there are plenty of food sources for the canines, including the city's hundreds of thousands of rats. He was surprised when he discovered that hundreds of the canines make Chicago their home. Gehrt tells Boyd that every major North American city has a population of coyotes and, the animals being as opportunistic as they are, there is very little humans can do about it.
