Crested plover (7)
I believe the answer is:
lapwing
'crested plover' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lapwing that I've seen before include "wader" , "Bird of the plover family" , "Plover, pewit" , "Flier" , "Large plover with a loud call -- peewit" .)
