I think I've finally figured out after all these years why my raspberries don't get stolen by the chipmunks in the fall. They get stolen in the summer, but not very much now. The reason is my dogwood tree.
I have a very beautiful kousa dogwood that I planted when I moved into this house. It is planted in my fruit garden next to the raspberries, because every fall it puts out pretty red fruit. The fruit is edible, or so I've been told, but it is not supposed to appeal to the human palate. However, the birds and squirrels (and I'm assuming chipmunks) love these fruit. I often see the squirrels doing acrobatics trying to reach the fruit on the branches. The birds hang upside down and eat them. They look very silly.
And they leave their droppings all underneath the tree. The skin is obviously not loved, but the interior is always hollowed out and eaten. They must love it more than the raspberries, since they have been left alone so far.
