Their call is a series of short high-pitched barks and yodels, much too high for a canine of their size. As soon as they are old enough to join in on hunts, the young begin to learn to call. A common call of the coyote is two short barks and a long wavering yodel. Sometimes if you call back on a dark evening, you can get them to answer. As soon as they realize the sounds are not from another coyote, they will stop answering.
Coyotes thrive on the habitat disturbances created by humans.
In fact, the logging that was done in British Columbia's Fraser Valley created open farmlands and fields which the coyote needs to survive. It wasn't until the 1930's, after the area had been logged, that the coyote first appeared in the Fraser Valley. By 1980, Coyotes had moved into Stanley Park in Vancouver. Coyotes can survive in urban areas as long as there is food and shelter available. They use ravines and other natural corridors to travel between developed areas.
