The maple tree outside my window has a hole that is used by a family of squirrels. I see three or four of them going in and out and sometimes just sitting in the entryway looking cute. While I was drinking my morning coffee today, I noticed that there was an incongruous branch of white pine up there, pictured above. Is it a squirrel Christmas tree? I'm sorry it's a blurry shot, but when I was more awake and went back to take a better picture, the pine branch was gone. Did they pull it inside to help insulate... or to decorate? Click to enlarge.
