A three-day-old piping plover is dwarfed by dune grass near a pond in the dunes north of Big Point Sable Lighthouse. The tiny bird has no idea it is a rare endangered species. Michigan Department of Natural Resources piping plover steward Katrina Hernandez and I have spent a couple hours this morning finding the plover and rest of its family after they fled from the cage and fencing designed to keep people and predators away, yet not to restrict the birds from leaving.
