According to the German 'Weland's Saga' (that would be Wayland Smith in England, Volundr in Scandinavia), swan mays are actually valkyries. The saga begins with a trio of valkyries taking a break on their way to some battle, and getting caught by Weland and his brothers who, of course, steal their feathered cloaks to prevent them from returning to swan form.
Good to know.
