Went down to the River Mersey today, and it was a very high tide and nowhere for the waders to wait for the water to recede apart from the fields which these did not seem to want to use. So quite a lot of them spent a great deal of time doing fantastic aerial acrobatics over the water. This is just a few, they are are mainly Sanderlings, but there were several other species that I spotted and probably a few more I never noticed. The waves of waders seemed to move as one, very close together but never touching each other. If you have ever watched large flocks of Starlings it was like that but on a much larger scale.
