Yeah, somethings are suggesting that the Kirin Subspecies could be the same species as Kirin. If so, I'm guessing since it only really appears with Kirin that it could be a Kirin during Mating Season, which it could be something that the Kirins in Barubare's Region go through while the Kirins in the rest of the Old World don't go through.
