Birdie? Yes and no (5)
I believe the answer is:
eagle
'birdie?' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
(Other definitions for eagle that I've seen before include "standard for the military is seen" , "high-flier" , "Bird of prey, may be golden" , "Fine achievement on course" , "might one be bald?" .)
