What Goes On Beneath Our Feet In Winter

Alfred's mouse2 2018-01-16 20.39.08 (003)It’s fairly unusual to see Deer or White-footed Mice, especially in the winter – they are nocturnal and they spend much of their time in the airspace under the snow next to the ground known as the subnivean layer. (A blanket of snow traps the earth’s heat, which melts the bottom of the snow, creating this layer of space.) Here both Deer Mice and White-footed Mice travel extensively, protected from both the cold (it stays within a degree or two of 32 F. regardless of outside temperature) and the eyes of predators. On cold winter days, groups including both species of mice keep warm by huddling in a common nest.

    They are sweet! But I thought that they all live in our attic insulation. Even warmer there.

      Your attic must be their summer residence 😮

    I assume you mean both species huddle together?
