Corn Bunting?

We do have lots of Hippolais Warblers here which are longer-tailed but they have plain backs and rounded tails, as does the long-tailed Great Reed Warbler. I added an enlarged picture which shows a notched tail but what looks like a wing-bar is more likely a twig which would rule out female House Sparrow and the head pattern is wrong for the others (Tree, Rock & Spanish). Pale eye ring rules out most Buntings but a Corn Bunting is just possible and they do breed here, so it might be that.
