Beautiful capture with lovely lighting and excellent detail as well as a wonderful low angle. Although I love the natural look in this composition I would be tempted to remove the two rocks on the right as I find my eye is being drawn away for the Dunlin. fine work and many thanks for sharing Jim.
I guess this is where I question what exactly it is that we're trying to capture.
Personally, I tend to lean toward and environmental shot and while perhaps this time it wouldn't be the case, I worry more about making things too darn sterile.
Shorebirds often times sit near little bits of washed up weeds, the rack line or stones for comfort.
Again, I guess it depends on whether or not the photographer is trying to capture reality...or not?
I like everything about the photo, the bird is beautiful, I see it exactly as it is, a shorebird taking a rest from his northbound migration in an all natural setting.
