stability of a bird

I jot 'em down not to forget

lateral (pitch):
* tail
* changing sweep, planform, and/or AoA of both wings

roll:
* wing dihedral
* wing sweep
* differenciating L&R wings (dihedral, planform, AoA) - in another words, making itself asymmetric against relative wind intentionally (but temporary)

directional (yaw):
* wing sweep
* vertically angled winglets
* wing differenciation
