Two-under-par golf score (5)
I believe the answer is:
eagle
'two-under-par golf score' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for eagle that I've seen before include "Two under in 20 across" , "may be soaring" , "The emblem of the US is bald" , "born hunter" , "It may soar" .)
