English Setters, Rusty and Purdy, find the birdfeeder down and broken. Dottie the deer didn't do it this time. Donna the Downy Woodpecker discovers huge footprints ten feet apart in the back of the yard. Rusty goes to check. Donna was right. Nancy the Red-breasted Nuthatch says the prints look like the Bigfoot prints she sees when she flies North for the summer. That's the only clue to who knocked the birdfeeder down; but the bigger mystery is who made those footprints!
