The Barbican development in central London is not exactly the spot, you would think, for seeing good birds.
Barbican Development

The development, built during the 1960s and 70s, lies across the line of the old city wall and some parts of the old wall are preserved amongst the blocks of flats and offices. I was recently doing some photography there of the remains when something caught my attention.
On the remains of the wall was a Grey Wagtail, a winter visitor to London.
