I'm going with ears, horns, tails and/or eyes of mammals. All the Faunus so far seem to be mammals and that makes sense to me, as you can't really pair a body part from a cold blooded reptile with a warm blooded human. Birds are warm blooded, but their anatomy is very different from how the human body is set up.
