(Putting this post behind a split, because it contains images of small, dead rodent-type animals. If the sight of deceased small, dead rodent-type animals bothers you, or you do not like to read about killing small, dead rodent-type animals, do not proceed.)
Notice to neighborhood squirrels: The bird feeder is now BIRDS ONLY. Climb up onto the feeder and chase off the birds at your own risk. Health warning: eating out of the feeders while being a squirrel may cause permanent brain damage.
