Night heron.

That heron is threat for all crabs living on the sandy shore. Heron is very quickly they catch a crab and shake him out of the shell. He prefers to hunting at twilight or at night

That bird does not let a human close to himself and prefers to stay at a distance. I could approach the closest distance of 200 - 250 fts

And here is an goggle-eyed crab, he is always on the alert :)
