Semi-Palmated Plover & Eggs - Charadrius semipalmatus
I discovered this Plover's nest just as the 4 eggs in it were hatching. The nest, eggs and chicks are very camouflaged and the adult birds also try to lure you away with the old 'come get me, I'm injured' trick, so the nests are quite hard to spot. You can see there is one chick that hatched and is all dry and fluffy, one that is still a little damp, one that has just broken open a small hole in its egg, and a lazy one that hadn't begun to hatch yet. Maybe the time lag is because birds lay one egg per day, so the first one is a little ahead of the last one. An hour later, I came back and they were all hatched and gone!
