Grey Wagtail in Yellow Sunshine!

Excuse the exclamation mark, but we had sunshine today - strong enough to actually emit some warmth, and that's EXCITING.

M has been suffering with toothache all over the bank holiday, so we found a dentist and walked to the appointment through the Newhall Valley. The sunshine was beautiful and everyone we met was smiling. The trees are budding, got some good photos of the heron in the marsh, but decided to go with this grey wagtail, who spent ages bathing himself in the brook, and then twirling around on this rock - wasn't even deterred by a lady talking to her two dogs right next to him.

I thought it was a YELLOW wagtail, but looked it up, and a yellow one has black legs, plus the grey one has a longer tail - so am pretty sure I've got it right - do tell me if not...
