Foxes communicate with one another by growls, yelps and short yapping barks. In autumn following birth, the pups of the fox's litter will disperse to their own territories. Dispersal can be to areas as nearby as 10 kilometers and as far away as 400 kilometers. Foxes remain in their own home ranges for life. A food supply is very important to the fox because it helps them survive in the wild.
Foxes mostly eat insects, including beetles and termites.
They also eat fruit, berries, grass, salmon, small rodents such as voles, mice, lemmings and hare, reptiles and food left over from humans. Foxes do scavenge food from humans, but only if they have nothing else to eat. Catching prey and small game is the source of food for the fox. Rodents, lizards, and insects such as locusts are popular prey. Foxes may range several miles a night looking for food.
