A snowy winter gives a bear den a cold-excluding outer covering--closes the entrance and the airholes. Most bears and ground-hogs appear to remain in the den all winter. I have known an occasional ground-hog to thrust out his head for a few minutes now and then during the winter, and bears may come forth and wander about for a time, especially if not quite comfortable. I have known a number of bears to come out toward spring for brief airings and sunnings. Mid-winter a bear wanted more bedding. In fact, he did not have any, which was unusual. But the winter was cold, no snow had fallen, and the frigid wind was whistling through his poorly built den house. The usual snow would have closed the airholes and shut out the cold. He was carrying cedar bark and mouthfuls of dried grass into the den. This same winter I came upon another bear. Cold or something else had driven him from his den. When I saw him he was trying to reopen an old den which was back in a bank under the roots of a spruce. He may have tried to dig a den elsewhere, but the ground was frozen almost as hard as stone. While he was working a bob-cat came snarling out. The bear struck at it. It backed off sputtering then ran away. In tearing out a root the bear slipped and rolled down the bank. He went off through the woods. Late one February I came upon a well-worn bear trail between the sunny side of a cliff and an open den. In this trail there were tracks fresh and tracks two or more weeks old. Elsewhere I have seen many evidences that bears toward spring come out briefly to sun themselves and to have an airing. But never a sign of their eating or drinking anything. Near my cabin I marked four ground-hog holes after the fat fellows went in. On September tenth I stuffed a bundle of grass in the entrance of each den. Sometime during the winter one of them had disturbed the grass and thrust out his head. Whether this was on Ground-hog Day or not, I cannot say. The other ground-hogs remained below until between April seventh and twelfth, about seven months. And these seven months were months of fast, and possibly without water. The raccoon, who ever seems a bright, original fellow, appears to have a hibernating system of his own. Many a raccoon takes a series of short hibernating sleeps each winter, and between these sleeps he is about hunting food, eating and living as usual. But I believe these periods of hibernating often correspond to stormy or snowy periods. While trying to see a flock of wild turkeys in Missouri one winter day I had a surprise. The snow showed that they had come out of the woods and eaten corn from a corn shock. I hoped to see them by using a near-by shock for a blind and walked around the shock. The snow over and around it showed only an outgoing mouse track. No snow had fallen for two days.
