Here are some monochrome photos to highlight this Horseshoe Crab season. Currently, the populations of Horseshoe Crabs, as well as of the birds that eat their eggs, Red Knots, Dunlins, Semipalmated Sandpiper, and Ruddy Turnstone, are all supposed to be in decline. There is no single cause and probably many unknowns as well.
