Help Please, is this a young Pied Wagtail

Thanks Catlady, Merlin suggested a White Wagtail with a very similar photo for a juvenile. I guess Americans call Pied Wagtails as White Wagtails.

White Wagtail is a sub species of Pied Wagtail, Dave. A quick glance through one of my books says the White is migratory to UK, whereas Pied is resident,
On the pied, the rump is black/dark grey whereas the white is grey, and there are other minor colour differences, depending on breeding/ non-breeding
