But the odds of there actually being am avian-Faunus are low, except for maybe a bat or other flying mammals. As Chishio said, all the Faunus so far seem to be a mix of human and some other mammal, which makes sense as mammals all have similar traits so you would expect them to be compatible. Birds, reptiles, insects, and so on all have a biology that may be too different from mammals to make a Faunus possible.
