Cooper's Hawks survive scare

Sometime between Tuesday evening and Wednesday Morning, a very large chunk of a big leaf Maple broke off and hit the tree that hosts the Cooper's Hawk nest. The piece that pretty huge, at least 3 feet in diameter. It whacked the western hemlock pretty good, and took out some branches. Jack Bettesworth was there when I came by, and said that the nest was still there, and they were still around. We saw one of them hunting smaller birds in the double big leaf maple on Arboretum Drive in the Sorbus collection.
I saw a rat on the Drive later that day too. It was about 6 inches long, with the tail. He was heading towards the other Cooper's hawk nest so it better be careful.
Lots and lots of birds in the islands in the north of the Arboretum.
