In the Northeast, raccoons spend the fall fattening up, for little, if any, food is consumed during the winter. Acorns, hickory nuts, beechnuts and hazelnuts are favorite foods. For as long as insects are available, they form a large part of a raccoon’s diet – delicacies include larvae of dug-up yellow jacket and bumblebee nests, and honeybees as well as the honey the bees have stored for the winter. Birds and rabbits injured by hunters, mice, bats, wild grapes and an occasional crayfish provide raccoons with enough sustenance so that fat makes up almost 50% of their body weight as they head into winter.
While signs of their presence, such as tracks, are still visible, they soon will be scarce. On the coldest winter days, raccoons will seek shelter in hollow trees, sometimes holing up for as long as a month at a time. Communal denning sometimes occurs, with up to 23 raccoons having been found in the same den. Considered “deep sleepers,” raccoons do not lower their metabolism significantly, and therefore are not considered true hibernators.
