One of the two sub-species of Red Knot occurring in North America, the Rufa subspecies breeds in the Canadian Artic Region and migrates along the east or Atlantic coast of the United States. The other sub-species, Calidris canutus roselaari , migrates along the Pacific Coast and breeds in Alaska and the Wrangel Island in Russia.

With birds bedecked in their breeding best and filling the air with song, this is migration at its loveliest. Threatened by loss of habitat both on breeding as well as wintering grounds, a few species have even become endangered or at least on a perilous track towards that worrisome designation.

This map shows the distribution of the World’s bird species, based on overlying the breeding and wintering ranges of all known species. And it raises a question: if all the birds are having a party over there, am I in the wrong spot? Brazil (1753 / 1832). Why am I here? And where all those birds are? Sri Lanka (375 / 436).

What I didn’t know was how this relationship actually works: the mechanics of Red Knot migration, the reduced digestive systems necessary for their long flighta, the need to fatten up quickly so they can fly to the Arctic and breed, how they compete with other shorebirds and gulls and, it turns out, humans, for horseshoe crab eggs.
