Then, I heard loud knocking and knew that we either had a Pileated Woodpecker or a Flicker near by. Imagine my surprise to look up to a tree and see a Flicker with its head peeking out of a hole in the tree! Unfortunately, I wasn't quick enough with the camera to catch her inside the tree hole, but did catch her beside the tree after:
I am glad that there are birds so close to our house that I can keep my eye on the nests. It is very entertaining!
