Grey Wagtail?

[Digeroo]

There was a wagtail on the pig plot next to my allotment this afternoon.  It is not a pied wagtail so I looked it up.  Seems the Grey Wagtail is supposed to be yellow underneath but this one was mostly creamy underneath maybe a slight yellow tinge in places.    It there an alternate identification.

It was slightly fatter than the rather sleek pied wagtails.  I wonder whether it is an immature bird?  If it is an immature Grey then I have never seen its parents.

the male's yellowness is supposed to go much paler in the winter, if that helps  :-\

Thanks that may be it.

I was lucky enough to see 2 grey wagtails Thursday in their normal habitat around water and they were both very yellow and as you say much rounder than the pied wagtail - a sight to be hold!

I don't thnk there's much room for doubt that it's a grey wag. They're common round the local reservoir, and they're usually more yellow than grey to my eyes, but it can be a very pale yellow. Yellow wagtail is very yellow and green, so it can't be that.
