Pied Wagtail (?)

It’s been dull and really quite cold today, with not many people out and about this morning where I was. I had a good walk but photo opportunities were limited so I spent a while trying to get close to this Pied Wagtail (I think) as I’ve never photographed one before. I would have liked to have got it flying but that was out of the question as even getting near enough for an acceptable shot was tricky enough. I’ll have to work on that!
