As I was walking through Shapwic Heath NNR on 20th April looking for pretty much any birds to photograph, I saw quite a gathering of birders looking at a small wader on the far side of Meare Heath drained lagoon.  At the time it was walking in front of the black-tailed godwit flock currently sporting beautiful summer plumage and it was hard to see.  Significantly smaller than the godwits, one observer commented that it could probably have walked between their legs.  After a few minutes it emerged in the clear and I rattled off a few shots of what I was told was a wood sandpiper.

Now, looking on the SOS messageboard I see that people think it may be a lesser yellowlegs so I thought I'd post up these pictures to aid the debate.  Bear in mind that these pictures are taken at extreme range (400 feet) and even with a 600mm lens with a 1.4 x teleconverter on a Canon 7D body you still don't get to see massive detail.
