Two Grey Wagtails in the garden

Two Grey Wagtails in the garden today; I can only guess that one is Wilma (who is around 6 years old ) and the other looks possibly one of last year's offspring - but not entirely sure.   They are only record shots taken through the window.

This is the "old girl" methinks

and the younger looking Grey Waggie

They remained together for a couple of hours, sometimes within a metre of one another but other times at opposite ends of the pond !      I think this is Wilma posturing to the other Wagtail as she really does like the place to herself  lol
