The red knot is a tiny shorebird that undertakes a mind-boggling migration from the tip of South America all the way to the Arctic Circle. One of the few stops on that marathon journey is the Delaware Bay, an estuary that offers a banquet for migrating birds. Here, for some 20,000 years, red knots have flocked by the thousands to fuel their journey. But humans may be writing a tragic ending to this extraordinary evolutionary success story, unless biologists armed with an unusual tool can win a race against time.
