About the program

The Cook County Coyote Project is a comprehensive study of coyotes in Chicago metropolitan areas. In 2000, we initiated the study in a non-biased attempt to address shortcomings in urban coyote ecology information and management. We continue to learn as the Coyote Project is still underway. With the help of many agencies, we live-capture our study subjects, collar, and release at the capture site. Coyotes are monitored in order to understand how they live in urban areas as well as how they interact with other wildlife and domestic animals. 

Our website provides details on the study, information about urban coyotes (including how to avoid conflicts), and a snapshot of the lives of the coyotes we track. By providing the public with our research, we are initiating the first step of coyote management — educating the public and untangling facts from myths. People should become aware of coyote signs and understand the differences between true threats and coexistence. It is important to stress that our relationship with coyotes is directly affected by our behavior. Coyotes react to us, and we can foster mutual respect or a lack of respect through cues we send to them. In our research, our primary interest is in observing and only in very rare occasions do we test manipulation of their behavior.

We hope you find answers to your questions on this website. If not, or to provide feedback on a new sighting of a collared coyote in your area, please feel free to contact us. Thank you for taking the time to learn more about these animals.

Coyote 441 is one of the most successful urban coyotes we have observed. This female was captured near the Lincoln Park Zoo in Chicago on March 10th, 2010. At the time of capture, she was a subadult in excellent condition, weighing 11 kg. A GPS collar was placed on her and we recorded her locations until November 2010 when her collar blew off (these collars are programmed to remotely fall off at a specified time).
