Like to see seabird behind a ship? (6)
I believe the answer is:
astern
'behind a ship?' is the definition.
(I've seen this before)
'like to see seabird' is the wordplay.
'like' becomes 'as'.
'to see seabird' becomes 'tern' (tern is a kind of seabird).
'as'+'tern'='ASTERN'
(Other definitions for astern that I've seen before include "Backward" , "Aft" , "Behind at sea" , "at the vessel's rear" , "State of S central US" .)
