I was asked yesterday to provide a source that says most birds have claws on the first and/or second fingers. I have come across a few places, such as Feduccia's 1996 book, which cite a "Fischer 1942" paper which is said to report finger claws from all "orders" except six. Granted, the claws (and the bones that carry them) are usually very small and straight.
