For a week we had a strange bird banging on the window next to our back door. We called him “Knucklehead”. Knucklehead would fly in at all hours, day and night, and peck and peck on the window. It drove us crazy. One morning we had opened the door to shoo Knucklehead off (again). On the hill, just a few feet away, was a squirrel. My husband jokingly said to the squirrel, “Take out Knucklehead and I’ll give you a pound of peanuts!” Oddly enough, that was the last time we saw Knucklehead!
