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.

Coyote 1

Coyote 1 was the first coyote captured on the project, on March 22, 2000, and has become the signature coyote of our research. When she was originally captured, she was just a year old and solitary. She weighed 13 kg (about 29 lbs), and was in excellent health, if not a little on the small side. In coyote years, she was a teenager. We tracked her movements over portions of five cities for the next nine months, as she floated across the landscape looking for a territory.
