Sharp-eyed bird (5)
I believe the answer is:
eagle
'sharp-eyed 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 "experts are putting more than albatross?" , "Keen-eyed bird" , "A glee-ful bird?" , "Bird of prey; former children's comic" , "good score" .)
