Helping the Red Knot by rescuing horseshoe crabs


The Red Knot, a shorebird, has been featured several times in nature documentaries both textual and video in which the marvels of migration are described.  The bird makes a very long migration every spring, and one of its most noted stops is on the shores of the Delaware Bay beaches.  After a long flight from South America, the hungry birds need food -- and so they time their arrival to coincide with the mating period of the horseshoe crab.   The crabs mate en masse right on the beach, so there are masses of horseshoe crab eggs in the sand, which the red knots gorge on during the stopover, then they finish their migration up to the Arctic.  A wonder of nature, to be sure.

But the red knot numbers have been going down, partly because horseshoe crab populations have been going done.  Though totally inedible from a human standpoint, they were being used as bait.  This got cut back by legislation, and now there's a program called "Re-Turn the Favor" in which the general population is being encouraged to flip over hapless horseshoe crabs whom waves or other actions have flipped onto their carapace back, and assist them in a return to the ocean.  In this manner losses due to accidental attrition in the horsheshoe crab population can be reduced.  

This is such a noble thing to do I may have to go do it myself one weekend.  And in the meantime I'll also do some boob, er, bird-watching at the same time.

Save me!  Save me!
