The pond has a very thin skin of ice in places. I can't see much sign of recent beaver activity and wonder if the lack of food may have driven him off in the last little while. Or maybe he was upset with the constant dam breakage. I keep looking at the sumacs which I would think he'd have a go at as he did in the fall. But no recent cutting can be found. On the other hand, the downed Manitoba maple has definitely been chewed at, but whether in the last few days or the last few weeks....
