If there are avian fauna, i'm pretty sure that any feature they'd have would be vestigial at best. (son's the only one so far that has been shown with a prehensile tail. Blake can twitch her cat ears, notice that she also has a pair of human ears.)

If only the Malachite sisters were Bird Fauna... with melanie having vestigial wings on the back of her waist, and miltiades having a plume sprouting from one side of her temple. (you know... since being mostly human in features apart from the few identifying traits of a faunus.)
