How many coyotes are in a pack? How many coyotes are in Chicago?

Our observations (during tracking, helicopter flights, and trapping) have revealed that the coyotes in our study maintain territories as groups unless living as a solitary animal. Group size in protected habitats is typically five to six adults in addition to pups born that year. It is estimated that between 1,500 and 2,000 coyotes may reside in Cook County, IL.

Habitat of Coyote 748

An ultimate, urban animal, Coyote 748 was fitted with a GPS-style tracking collar in the Bronzeville area of Chicago on February 24, 2014. At his capture, it was obvious he was of breeding age and once a few radio-locations were collected, we realized we had collared a resident coyote with an established territory. He seemed to go about his daily routine in a low-profile fashion, taking to the busy streets nightly without fail. In April, his normal quiet behavior turned aggressive towards dogs as people walked their pets through a specific area.
