"Spring Flirtation" - Pileated Woodpeckers

We watched this scene unfold just outside our kitchen windows!  The birds spiraled up and down the tree trunk staying on opposite sides.  Now and then they would stop and in a moment one would peek around to see if the other was still there. I was spring and we think this was courtship. The performance lasted a good half hour before they flew off for privacy.  It was wonderful!
