Location
Fox dens are in secluded spots such as under tree roots, in abandoned burrows, inside hollow logs, or beneath dense vegetation.
Structure
Dens are underground networks with tunnels and chambers, multiple entrances, a main nesting area, and soft linings of leaves and fur.
Exteriors are unremarkable holes, while interiors are dusty and earthy. Observe from a distance and avoid disturbing them, especially during breeding season.
