Northwestern Shrike - Ken Walker and I heard the strangest set of call notes and song coming from the Hawthorne thicket, we were really surprised. First I thought of Mockingbirds, and then of Thrashers I had heard in the Pinon pine country of S. California. I couldn't begin to describe the notes, from quite a pretty little song to singular notes, and also harsh buzzing notes, etc. The bird didn't want to fly from the center of the thicket, but finally worked its way up to the top twigs where I had a fine opportunity to observe its finely barred breast.
