Red Knots are tiny shorebirds that fly 9000 miles from Tierra del Fuego to the Arctic and back. The story of the Red Knot is inextricably tied to the story of the horseshoe crabs that come ashore once a year to lay millions of pinhead sized eggs, that nourish and fatten starving knots before the final leg of their trip. Deborah Cramer follows that journey in her book The Narrow Edge: A Tiny Bird, and Ancient Crab, and an Epic Journey.
