This hill is 100km (60 miles) west of Ithaca, the home of Cornell University, where Keeton, a bird biologist, worked. Unlike those who launched Apollo 11, however, he had no expectation that his charges would return safely, for that part of the state had long been known as the Birdmuda triangle. Pigeons released there tended to vanish, and Keeton wanted to know why. August 13th, though, turned out to be both his and the pigeons' lucky day. All the birds got back to their loft in Ithaca--the only time this happened during years of experiments. Keeton, who died in 1980, never did work out what was special about that particular Wednesday. But his successor Jon Hagstrum, of the United States Geological Survey, has. And the result, which he has just published in Experimental Biology, helps explain how homing pigeons pull off their spectacular feats of navigation.
