I found these ones down by the edge of the lake water. I don't know if the birds eat these ones, but they have been eating the ones we have in the back yard. The squirrels and chipmunks are also joining in.
I have one little red squirrel that breaks off a branch with the berries, climbs to a nook in a tree branch, picks all the leaves off, then eats each berry and discards the branch. Quite a pile of leaves and twigs are building up under that tree.
Of course, when I go out with the camera, he beats feet and is no where to be found. I think he is laughing at me because he watches me watching him through the window.
