In order for the shorebirds known as red knots to survive their annual migration from the Southern Hemisphere to the species' Arctic breeding grounds, they rely on a series of site along the way to provide enough food for their stay and to fuel their onward flight. If just one of these sites is compromised, the species itself will fail. In The Narrow Edge, Deborah Cramer travels the migration route of the American rufa knot, revealing the factors that threaten the knot's coastal stopover sites. Reviewer Nigel A. Clark welcomes this tribute to a tiny shorebird, which he believes offers important lessons and strategies that may be implemented for the protection and preservation of other species.
