Coyotes usually try to avoid human contact. Yet animal experts say an increasing number of coyotes are setting up shop in one of most dense urban labyrinths: downtown Chicago. The seemingly incongruous marriage between coyotes and a people-packed habitat has occurred naturally, according to Stan Gehrt, an Ohio State University professor who specializes in coyote research in Cook County. Gehrt said he and his team know of no deliberate efforts to release coyotes into the downtown area.
