Corn Bunting Miliaria calandra
The corn bunting is a sparrow-sized, streaky brown bird of hedgerows and farmland that feeds on seeds and invertebrates. In the winter, it will join mixed flocks of buntings, finches and sparrows to feed on seeds on farmland. Male corn buntings are often seen perched on top of bushes singing loudly - a song that sounds just like a jangling set of keys. Image: Neil Rolph (Flickr).
