A Little Bit Of Bread And No Cheese Meaning

(Britain, idiomatic, onomatopoeic) the song of the yellowhammer.

Example: 1896, Edward Marston, By meadow and stream: pleasant memories of pleasant places
  It is delightful to hear the yellowhammer's song — his only song : "A little bit of bread and no cheese."
1937, Lovely places I remember (in The Rotarian, volume 50, number 2, February 1937)
  "A little bit of bread and no cheese!" cry the yellowhammers petulantly. But no one takes any notice of them.
