As the last of the large lakes in the south begin to freeze, a few hardy ducks remain. There is a story about a Common Merganser that wintered on the Klondike River. This individual lived in the airspace between the ice that formed in the autumn and the water surface that dropped during the winter. The ptarmigan move down from their mountain locales into the lower elevation willow thickets. This is a time when the lynx, marten and coyote can be found through their tracks left behind in the snow.
Red squirrels take naps, sometimes days at a time, only to emerge to feed.
