After zooming to see the bird this morning with the kids in tow (my two year old has it on her list!), I returned tonight to help out with the twitch. The bird was far too far away to get anything decent, but I took these for a sense of the atmosphere. I wasn't actively birding when Rainham hosted the Sociable Plover, and as I was living just down the road at the time I have always regretted it, so this in a way was my turn.
PS While you're here, have a look at the Med Gull a few photos down. A Wanstead Tick for me, and more exciting than the Plover in many ways.
