Some guy who should have known better was feeding this coyote by the side of the road next to one of the hiking trails. The next day, the warden had to close the hiking trail because the coyote became aggressive toward some of the hikers. The warden thinks the aggressive behaviour was likely the result of people feeding it and the animal quickly associated people, hikers in this case, as a source of food. Also, it is illegal to feed wild animals along the part of the Cabot Trail which runs through Cape Breton Highlands National Park. And now you know why. The warden had to actually go after this coyote. A shot was fired at it but no trace of the coyote was ever found.
The coyote found in Nova Scotia is a hardier breed than ones found elsewhere. See this link. http://www.gov.ns.ca/natr/wildlife/conserva/07-04-6.htm
