We have a really nice crop of holly berries on the tree in front of our house this fall. The squirrels are constantly in this tree and the ground underneath it, including the front walk, is constantly littered with pieces of berry and the occasional leaf. The robins also like them and generally, at some point in the winter, we’ll look out and they will be systematically devouring them. There is another holly at the corner of the house and the robins have found that one and were up in it the other day. So far this one has just been the squirrels, though.
