Pavlova portrayal (4)
I believe the answer is:
swan
'pavlova portrayal' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for swan that I've seen before include "The Ugly Duckling's outcome" , "Large waterbird" , "possibly mute" , "Large water bird" , "Bird of Cygnus genus" .)
