Winter Survival Strategy of Flying Squirrels

 

During the winter flying squirrels often huddle together in large communal nests, sometimes with populations numbering over two dozen squirrels, in an effort to keep warm.  Two years ago 22 of these nocturnal creatures spent the majority of the winter in my log cabin, doing just that.  Although flying squirrels do not hibernate, if temperatures become too severe the squirrels will enter a state of torpor until temperatures return to normal.

We have two species of flying squirrels in most of New England, the Southern (Glaucomys volans) and Northern (Glaucomys sabrinus), which is larger and usually more brownish than its cousin.  One could deduce that these gentle rodents are nocturnal just by looking at the size of their luminous eyes.  Because they feed at night, we don’t set eyes on them very often, except for an occasional lucky glance at the bird feeder before heading to bed. If we did observe them more often, we would marvel at their stretching their legs out, extending a flap of skin that runs from their front legs to their hind legs, and effortlessly soaring from one tree to another — as far as 150 feet horizontally from a height of 60 feet.  One documented sighting that I would love to observe is a female carrying young while gliding!
