Winter dens - The most commonly used winter dens are in hollow trees. Tree dens may be in any hollow limb or trunk of sufficient size. In many areas, hollow trees are the most popular choice. Underground burrows are also used. In marshes, swamps, and open fields the most common resting site is on the ground in herbaceous vegetation.
Raccoons are omnivorous.
Nuts, especially acorns, are important seasonal foods. The most important animal food is crayfish. Insects, especially grasshoppers, beetles, caterpillars, and true bugs, are also commonly eaten. Young common muskrat are sometimes eaten in the spring, while adults may be taken from traps or as carrion. Waterfowl are most often taken as cripples or carrion during the hunting season.
