Mallard ducks stay near ponds as long as there is some open water. They can swim in cold water and stand on ice because they have thick feather insulation and their feet are adapted to keep out the cold. In contrast, many other species of birds migrate when the weather begins to chill. A few kinds of butterflies do as well. Cold-blooded toads, water snakes, and garter snakes head under decaying logs, in stone piles, burrows, or other holes, and hibernate.
Raccoons only become active on mild days, on cold ones they hibernate in their dens.
A raccoon's hibernation sleep accompanies near normal body temperature with only slightly slowed circulation and respiration rates. Deer change their diet for the winter. They eat tree buds, twigs, bark, and conifer foliage. Moose do the same, with the addition of aquatic plants as well. It s that time of the year again when the snow is falling and falling and falling and falling.
