An evening searching for the "Coca Cola" coyote pair who use railroad tracks as their highway between hunting grounds in empty lots and overgrown areas of South Chicago. Using a radio telemetry antaenna mounted to the roof of a truck, I followed a wildlife tech with the Cook County Coyote Project tracking the movements while hunting and transiting at night. Coyotes in Chicago often use railroad tracks as their highway during the night to hunt mainly for rabbits and small rodents around Chicago.
