Did you know that some animals live out the winter beneath the snow?Â Scientists use the word subnivean to describe the world under the snow cover.Â Snow acts as a thermal blanket, protecting animals like mice, voles, and shrews from the winter cold.Â These animals build elaborate tunnels and nets under the snow.Â The tunnels are like little roadways that they travel through protecting them from predators.Â However, this frosty covering does not always hide them completely.Â Owls, foxes, and coyotes can hear mice moving through the tunnels from above and often pounce through the snow catching an unsuspecting mouse.
Snow is very important to the survival of these small mammals.Â This winter when there is a nice layer of snow on the ground, think about who may be living under it.Â And in the spring as the snow starts to melt you many find many of these tunnels scattered through out a forest, field or even your own backyard.
