Many foxes live near people because they can find a lot of food in a small space. In the wild, foxes need a large living space or territory. They have a home range of one to five miles. Red foxes move over that range looking for food, usually hunting alone. It's like leaving a note to remind themselves not to go there again.
Red foxes can be very territorial, fighting other foxes that come into their area.
Their senses of smell, eyesight, and hearing work together to help them find tiny mice scurrying through the tall grass. When they think they've found the mouse, they pounce on it, grabbing it with their paws. Red foxes only use dens when they have babies to protect. The rest of the time, they find an open place in the grass or brush to rest, so they can watch out for predators. A fox den is usually an old burrow from another animal like a woodchuck or armadillo.
