Oak boughs

All semester, I’ve been eyeing a cantaloupe-sized knothole in one of the sprawling oak trees on the quad at Framingham State. The fifth floor of Hemenway Labs provides an eye-level view of this hole, and I keep hoping to see an owl, raccoon, or other critter peering out of it, as it looks like a perfect animal den.

Good real estate doesn’t stay empty for long. On Thursday, I watched as first one and then two gray squirrels carried dead oak leaves into this hole, presumably making a nest for the winter. Gray squirrels, I read, often construct multiple nests in their home territory, typically using them as solitary shelter but sometimes sharing a den in cold weather. Apparently even squirrels appreciate cozy companionship when the temperatures drop.
