Large bunting (12)
I believe the answer is:
yellowhammer
(Other definitions for yellowhammer that I've seen before include "Bird with the "a little bit of bread and no cheese" song" , "Bird with a call supposed to sound like "a little bit of bread and no cheese"" , "Type of bunting" , "Bird - why "Rommel ale"? (anag)" , "Bird of the bunting family" .)
