Also in the Arboretum, I stopped by one of the best used squirrel trees. This is a large maple that for years has hosted families of grey squirrels. Last year, one of its branches was cut off, and I was worried that the entire tree would be taken down. But so far, it is still standing. As you can see, it is still being well used by squirrels. In one photo, you can see both the grey and the black phase squirrels peering out.
