I spent 5 hours photographing this Pileated Woodpecker hole, watching both parents coming in to feed the last remaining baby. Much to my amazement, a Common Merganser came out of the hole, leaving the baby still inside. Dad immediately flew over and peered inside the hole. The Merganser poked it's head out, and for a few seconds the two birds were beak-to-beak. Shortly after that, the Merganser flew off. Several hours later the baby fledged the nest.
