Some people have said mothmen resemble birds... you know, I can kinda see it, actually.

A birdlike crest that resembles feathers seen on cockatoos!

• This crest is capable of movement and can flare up and down.
• Can be applied to other crests to allow them to move as well, this combination doesn't have to retain this shape!
  • Note that this doesn't mean you always have to make the secondary crest capable of movement, you can have a set of double crests with this crest in between them, etc.

NOT ALLOWED:

• Cannot be applied to crests that already are capable of movement:
  
  • Tendrils
  • Real Ears
• Note that this doesn't mean you can't have both applied at once, you can have a set of real ears with this crest in between them, etc. The "movement" aspect simply becomes moot.

If you're unsure if your idea is valid, feel free to ask.
