Each year, a small shorebird that winters on the southern tip of South America must make a 10,000-mile journey to its nesting grounds in the Arctic – one of the longest migrations on earth.  The pocket-sized long distance traveler times its migration precisely to coincide with the annual spawning of one of earth’s most ancient creatures.  Horseshoe crab eggs in the Delaware Bay fuel the little bird’s epic journey to the Arctic... but recently, bird numbers have started to crash.  The story of the red knot and the horseshoe crab is a living example of how every species is interconnected – each one important, no matter how big or small.
