Yesterday I was surprised to see a large, gray and white bird hovering in front of my rhododendron bush.  My initial thought was a Mockingbird, but I quickly realized it was a Northern Shrike.  It was only seconds before a Chickadee came out of the bush and flew for cover of a hemlock tree, with the Shrike in hot pursuit.  I wasn't able to see the outcome.
