The photos were taken in the morning of 26 March 2021 in the Shen Zhen Talent Park, Shen Zhen. There are many sand plovers. I suppose the first photo is a Greater Sand Plover because it has a longer and heavier bill with a paler leg. The one in the second photo should be a Lesser Sand Plover as it has a shorter and less heavy bill with darker legs.
