Buccaneer has bird (5)
I believe the answer is:
drake
I believe this clue is a double definition.
'buccaneer' is the first definition.
(Sir Francis Drake)
'bird' is the second definition.
(I know that drake is a type of duck)
'has' acts as a link.
(Other definitions for drake that I've seen before include "Explorer" , "Male duck - circumnavigator" , "Elizabethan sailor" , "Particular kind of duck" , "Aquatic bird" .)
