Unfortunately, it also allows its main predator, people and their dogs, to follow the fox's trail. These droppings are left at any point of heavy use. Scats might be left at gaps in a hedge or fence, and along the edge of a field. As with dogs, foxes use urine to mark their territory, especially during the mating season. Communication between foxes is as much a means of keeping them apart as it is of bringing them together.
Foxes are usually silent.
They can make a large variety of calls including barks, screams, a howl, yap, and growl. They even seem to hiccup. During the mating, season various sounds bring males and females together while warning off other males. During the winter, the male is busy establishing his territory. Often in the evening, the male makes a yelling bark, with either short and broken sounds or a single long note.
