Funny.  Perhaps you missed that my comment was a polite way of saying the 
argument doesn't make sense in general.  I know what you're *trying* to say: 
you think that feathers seem so specifically adapted to flight, that you can't 
imagine them evolving for anything else.  Which is a silly argument.

And what would a relevant list be, then?  How about *most* passerine birds (for 
which wing display is second in frequency only to vocal display).  But 
regardless, if your argument is "I'm right and you will change your mind 
because obviously all counter examples don't matter", then the discussion is 
clearly over.
