Not only fist time spotting one but I also got a few images. I was very excited when I seen these guys sleeping with some Sandrelings and Least Sandpipers. Light angle was not the greatest because me and the birds where on a little rock that I had to step into the cold Atlantic waters to get to and some were sleeping directly to my right and left. I had to remove two whole birds and a bill from this image as they were so packed together that I couldn't get any clean shots. They were never worried about my presence but shortly took flight because of a loud and aggresive Greater Black-backed Gull that started harassing them.
All C/C greatly appreciated

Nice image, interesting pose and great editing work. I know the Dunlin sub species you get in the US generally have longer bills than our ssps arctica and schinzii, which we get in the UK, but if I saw this along our coast I would tend to think possibly Curlew Sandpiper - with the slightly huntched up stance accounting for the legs looking slightly shorter than you would expect for CS. Check this one out with some of your US shorebird experts - I would be interested to hear their comments.
