National bird (5)
I believe the answer is:
eagle
'national bird' 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 "Hook-billed bird of prey -- old US $10 coin" , "kind of bird" , "one's well below par" , "It may soar" , "standard for the military is seen" .)
