"Bald" bird (5)
I believe the answer is:
eagle
'bald bird' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eagle that I've seen before include "five buck bit, or more" , "King of birds" , "Large bird of prey" , "It normally takes two or three shots to shoot this" , "somewhat under par" .)
