HERD ON THE BEACH

A "herd" of curlews, so Wikipedia tells me. Or possibly a "head" of curlews, or a "curfew" of curlews. Who makes these things up? I think a curve of curlews would work just as well.

I guess that the front one with the leg rings is probably a parent and the others are possibly this year's youngsters who haven't been ringed yet.
