Answer: The number of years I've lived in the woods on Old Oak Hill without seeing a Pileated Woodpecker while looking out my kitchen window.
The memory card wasn't in the camera. The door was locked and the screen door squeaked as I opened it. By the time I made my way through the scrub to get near Old Oak, the camera battery was dead. But, the pair was re-united and the worried half of the pair had stopped its kuk-kuk-kuk song that, roughly translated, was a pleading where are you?
So, here is another picture from the woods, just as wonderful, but not as surprising: Virginia Bluebells, a flower with delicate blooms and a leaf that says Don't mess with me! I'm a hardy perennial.
