Another bird that is often faithful to the same spots, Pied Wagtails can usually be found where there are people, for example they are commonly found in supermarket car parks. At Cragside you will often see them near picnic sites and around the visitor centre (where these photos were taken).

Pied Wagtails are all over black, white and grey. However, a Grey Wagtail is very different, having a yellow underside.
