Wagtail

I popped up to Elm Row for a few essentials and saw a couple of wagtails zooming about on the pavement outside Valvona and Crolla. Gosh, they move fast! One was a standard pied wagtail of the black-and-white variety, but the other was definitely paler, with a sort of grey-brown back. Maybe it's Mrs Pied Wagtail - I think they were together!
