Greater Sand-Plover

Differentiating Greater and Less Sand-Plovers without direct comparison is very difficult, and even I am not 100%sure of the ID of the above bird. A well-known shorebird bander I consulted suggests - above all other field marks offered by various field guides - leg color the best indicator, Greater sporting green and Lesser showing generally black. Either way, I think this is a cool frame with the bird sucking the worm out of the sand!
