Grey Wagtail in the Garden

Washing up this morning before setting off for work experience I spotted a grey wagtail drop into the back yard. To say I was surprised doesnt really cover it, I watched it for around 10 seconds before rushing up to get my camera. Sadly when I got back all I saw was it fly away under the caravan, where it never came out of. It was a pity that I diddnt manage to get any photos, but it was still a great record for the garden, another unusual garden bird to add to the list.
