Colyton WTW

If you've seen Steve's blog you'll be aware that there is a Yellow Wagtail on Colyton WTW (opposite the Woodlark field). It is at least a potential candidate for Eastern Yellow Wagtail, so it would be nice if some skilful soul could get some stunning photos from all angles, and clear recordings of the call. Thanks in advance!

In the meantime, here is a digiscoped shot taken through the morning mist. Please do better than this...
