Purple Sandpiper

Thanks!

Thanks Liam. Never heard of a Purple Sandpiper.

Purple Sandpiper for the dark birds, Sanderling for the pale ones.

Brown ones look like Surfbirds or Turnstone but the only one I see listed is Ruddy.

The mostly white birds are Sanderlings and the more brown birds are a type of Sandpiper, won't be able to tell species from these photos.
