Red Knot

The red knot is a remarkable migratory shorebird. In the U.S., the shores of Delaware Bay provide a critical stopover area. The birds, many of which winter as far south as the southern tip of South America, arrive at the Bay to coincide with the spawning of horseshoe crabs in late May and early June, producing one of the most dramatic natural phenomena anywhere in the world. Feeding on fat-rich eggs of the horseshoe crab, the birds refuel and continue their journey to Arctic breeding grounds. At one time, more than 100,000 once stopped at the Bay. Today, that number is just over 13,000.
