In late spring Red Knots arrive along the shores of Deleware Bay. Its one of several stopovers on their annual migration from their wintering grounds of Tierra del Fuego to their breeding grounds along Hudson Bay. They will have flown a total of 9,000 miles by year's end.  Important fuel for their bodies is found in the form of horseshoe eggs which the crabs lay only in spring during a narrow window in May. Unfortunately, the horseshoe crabs are in decline because of many reasons including polluted Bay waters, the blue blood of the crabs used for medical purposes, and bait for fishing. This "knot" of supply and demand nature that has so simply provided at the perfect time  of year is repidly unraveling. Last year (2018) red knots had declined by 26%. Help keep the knot together!
