It soars over shores (4)
I believe the answer is:
gull
'it soars over shores' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for gull that I've seen before include "Common seabird" , "Take in" , "Dupe - aquatic bird" , "Seabird with a raucous call" , "Dupe - sea bird" .)
