Black-and-white shorebird (6)
I believe the answer is:
avocet
'black-and-white shorebird' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for avocet that I've seen before include "Might it sing" , "Wading bird with long bill" , "RSPB emblem" , "Long-legged wading bird with upward-curving bill" , "ornithological specimen" .)
