Shoot a bird (5)
I believe the answer is:
snipe
I believe this is a double definition.
'shoot' is the first definition.
(I know that snipe is a more specific form of shoot)
'a bird' is the second definition.
(snipe is a kind of bird)
(Other definitions for snipe that I've seen before include "Verbal criticism" , "The bird to shoot from cover" , "From concealed position, shoot" , "Wading bird with long straight bill" , "Wading bird; shoot from concealment" .)
