Invisibility
All BouWa are born with a natural form of a body cloak but cannot learn to use it until they become cubs. They simply fold their wings completely around there forms -rather crouched or hanging from some other surface, though rarely standing- they invoke a natural ability which causes their wings, feathered, membraned, or whatever, to completely blend with their surroundings, this also allows them to move freely without being seen and true seeing or detect invisibility can-not- unmask this little trick
