The Corn Bunting (Miliaria calandra) is a sparrow-sized, streaky brown bird of hedgerows and farmland. It is most similar to the Skylark, but with a thicker bill and no crest. Larger than other buntings, but this group can be difficult to tell apart – unusually for buntings the sexes appear similar in plumage, although the males are approximately 20% larger than females. Corn Buntings feed on seeds and invertebrates. Male Corn Buntings are often seen perched on top of bushes singing loudly - a song that sounds just like a jangling set of keys.
