We’re right on the edge of when beavers will no longer be able to smell fresh air, see the sun and obtain fresh bark. Until the temperature drops to around 16 degrees F. they continue to break through the thin ice covering their pond. Once the temperature drops to 16 degrees F., they no longer try to break through the ice and are sealed under it until spring, unless there’s a mid-winter thaw. Once they are confined by the ice, their activities outside the lodge are minimal. Beavers leave their lodge in winter primarily for two reasons: to swim out to their winter food supply pile and retrieve a stick which they bring back into the lodge to eat, and to defecate. Other than those excursions, they spend most of their day in the dark, enduring a lodge temperature of about 34 degrees F. (Thanks to Kay Shumway for photo op.)
