This set includes sanderlings and dunlin which are most obvious by there long down curving beak. The photos were taken at Nickerson Beach at the end of November on a lovely warm day with a super sunset light.
This is really a nice set, Morris. That first one may be the best(or at least my favorite) sandpiper flock image I've ever seen. The lighting and the surf in the BG really set it off. Really well done.
