We often can hear coyotes at night, calling to one another. DH got lucky recently when he saw a coyote loping across a field at 5 pm. In trying to find more information about these distinctive coyote fences which seem to be everywhere in the neighborhood, I found this information:
Fencing - Coyotes can jump over and dig under fences that are improperly built. Coyotes don't
leap fences in a single bound but, like domestic dogs, they grip the top with their front paws and
kick themselves upward and over with the back legs. Their tendency to climb will depend on the
individual animal and its motivation. Coyotes are also excellent diggers, therefore the type of
fence you install may require barriers be built into or extending from the ground.
