Coyotes began migrating eastward throughout the latter half of the 20th Century. Once restricted to the western plains, they now occupy most of the continent and have invaded farms and cities, where they have expanded their diet to include squirrels, household pets and discarded fast food.
Land-use changes in the U.S., the disappearance of wolves, a growing human population, and a remarkable ability to adapt to new environments and conditions encouraged coyotes to expand into new habitats and thrive, while other predators faced with similar pressures dwindled and faced extinction.
