Unfortunately, this is not a great photo, but is the best of the few I managed to take. I wanted to get a photo of this squirrel with her mouthful of nest material which she had scraped from a juniper. While walking along the service road between the Old Field and the Ash Woods, I heard what sounded like someone in the tall juniper breaking off branches. I couldn't see a person, and for a brief mad moment thought someone had climbed up into the tree intent on damage! Well, someone had, but it was a four-legged critter. This grey squirrel was vigorously pulling off strips of bark. When she had a big mouthful she leaped across the service road and into the Ash woods. I followed her as best I could as she rushed off a top speed through the treetops. Eventually she stopped and looked down at me as if to berate me for following. This is when I managed to get a few poor shots at a very high ISO. She just sat there so I left, as it was clear she was not going to move toward her nest until I did so.
