While waiting for the Prothonotary Warbler on Knee to emerge from its nest cavity I heard an odd scraping noise. This squirrel was peeling bark off a tree.
He kept pulling and stuffing it in his mouth. The strands seemed very pliable, good material to welcome baby squirrels.
Hey, I’m beeing watched!
Then he balled it all up in his mouth and scooted around the other side of the tree where I lost sight of him.
