Hello, I'm having trouble identifying this guy. This was taken in a hotel courtyard in southern Germany in late September. Sorry for the grainy picture, but the lighting conditions weren't great and I wasn't in the best position. I"m not that familiar with European birds--my first thought was a white wagtail, but I've never seen one without white on its face, though I've not seen all that many and are unfamiliar with how immature wagtails look. Can't find anything else in my field guide that bears much of a resemblance. What do you think?
