Bird artist (8)
I believe the answer is:
whistler
I believe this clue is a double definition.
'bird' is the first definition.
(I know that whistler is a type of Old World flycatcher)
'artist' is the second definition.
(painter James McNeill Whistler)
(Other definitions for whistler that I've seen before include "American painter, 1834-1903" , "Olympic ski resort" , "old kettle, say" , "He used canvas" , "James --, US artist" .)
