Grey Wagtail - Honoured Visitor to my little patch of the Fens

Click pictures for more detailed view.

This Grey Wagtail (Female) kindly dropped by when I had a cup of tea and my Nikon camera on my lap.  It was just 3-4 meters away and 

 it simply ignored me and carried on about its business!  I always confuse Grey and Yellow Wagtails in my head as the bright yellow rump is so very yellow, and my thoughts jump to yellow rather than grey. On closer inspection the two birds are quite different.  As the name suggests, this bird was wagging its tail up and down the entire time it was on the ground.  Beautiful autumn colours of the northern 'red oak' leaves helping to add some contrast and texture to the picture.
