My wife and I were standing beside you and clearly remembered puzzling over (what proved to be) the Band-Rumped Storm Petrol. Thanks for giving us a "life bird". I do remember the bird flying higher than the Wilson's and with a different kind of flight. It came up on the left side and a few of us puzzled over it. In hindsight, I wondered why Rick didn't say anything about it but that was answered when he said he didn't see it. Thanks again....gotta get one of those cameras!
