Yep, there are about 400 nesting pairs of Piping Plovers left in the world.The Island that I trap is one of there prime nesting grounds.The Piping Plovers nest on the beach, just above the high tide mark.Using shells to line there nest,and the sand colored eggs with light brown specks are hard to see.Red fox eat the eggs and chicks.But the red fox wont eat ANYTHING when I put my 5/64" necklace on him. :-)
