Large flock wheeling just off shore.
No interactions present.
If they are Curlew, they must all be males, as the bills do not appear especially long. I am not sure that I can eliminate Whimbrel, especially from the second picture.

Yesterday (06/ 05), a similar sighting a few miles W. along the same coast. No camera handy, but Syrphus' comments above helpful: concentrating on the calls it seems that a small flock of Whimbrels frequents the Sussex coast at tide-fall.
This is the time for them - they are not called 'May-bird' for nothing. And on passage they are quite numerous. I have always thought their call quite beautiful. One of their other names is 'Seven-whistler'.
