Cawing bird (4)
I believe the answer is:
crow
'cawing bird' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for crow that I've seen before include "Native American -- bird" , "Bird in 1's poems" , "'As the - - flies'" , "Make sounds of pleasure as a baby does - or a bird" , "Black bird; boast" .)
