Every winter the wetter parts of the Rodwell Trail are home to one, sometimes two, Grey Wagtails. This has been hapening for at least twelve years now, so must involve several generations of birds. Even so, each winter the wagtail seems to get more and more tame.
The next video was made nearly three years ago and shows how difficult it was to get close to the bird then.
Of course it's a shame I only get to film them in winter. Here's a sunnier video I made on the River Dart in Devon in July 2015.
