How can you identify an animal den?
Loose dirt close to a hole in the ground is indicative of a burrowing animal – usually a rat or a woodchuck. Other animals, such as chipmunks and squirrels may clear the dirt and try to hide their burrows in the ground.
Look for signs of nesting, such as leaves piled in, and furr.
Also around an area, you may suspect is a den, search for signs of
scat, or feces. Animals will leave lots of piles around den areas,
to mark there territory.
