These are Streifen's wings with a more realistic anatomy (Back and front view). heres some stuff about them:

-Feathers. (durrrr)

-Two long feathers near the tip of the wing. (Striped ones)

-Very powerful, can fly fast.
-Don't do well in water.

-Swirl is where the joint of the wing is, where it bends.
