I went out and she pointed to the dead tree in our neighbor's yard. "I think there's a Pileated on the tree."
Sure enough, a female Pileated Woodpecker was working her way up the trunk of the tree. That's a new bird for our yards and so I grabbed a couple of photos.
I was just about to go back to watching tennis when another bird flew into the dead tree. It was the female's partner, distinguished by the red patch on its cheek.
