Songbird, black, in wind (11)
I believe the answer is:
nightingale
'songbird' is the definition.
(I've seen this before)
'black in wind' is the wordplay.
'black' becomes 'night' (night can mean as black as night).
'wind' becomes 'gale' (gale is a kind of wind).
'night'+'in'+'gale'='NIGHTINGALE'
(Other definitions for nightingale that I've seen before include "Bird with beautiful song" , "Florence" , "See 13" , "Celebrated songbird" , "Small thrush with a melodious song" .)
