Curlew's cousin (5)
I believe the answer is:
snipe
'curlew's cousin' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for snipe that I've seen before include "Curlew or sandpiper" , "Perhaps carp" , "From concealed position, shoot" , "To pick off soldiers, say" , "Wading bird with long straight bill" .)
