As we passed this tree, I heard a little scrabbling sound.
I parked the dog and went back to look.
A little squirrel, unable to get a purchase on the plastic sheath. Didn't look sick or injured, but must have been? It looked young, too. Maybe just not smart enough to make a dash for another tree.
It kept ducking around to hide from me, but I could reach around with the camera.
Then it peeked out to see where I was.
I left it alone and we went on our way.
