Skeleton

Had to drag myself out of the flat today (really sick of this cold now) to go to an elemental meeting. L found this piece of skeleton on a beach. We think it's part of a bird (it was about 4-5" long) but we've no idea what the two extra flappy bones are, anyone clued up on their bird anatomy care to shed some light?

Elements are coming along well. We've got the performance pretty much sussed and just need to finish costumes now.
