THE NATIONAL GEOGRAPHIC MAGAZINE Photograph by J. D. Rattar SHOUT "HALLOO!" AND THE CLIFF INSTANTLY BLOSSOMS WITH WHITE AS MURRES ABOUT-FACE When the birds are incubating, their dark backs generally are turned toward the sea. If disturbed they face about as one, the myriads of white "shirt fronts" appearing in sudden contrast. When murres are frightened from their ledges their flight is often accompanied by a shower of eggs. Here their attention has been attracted by two men in a small boat, who are exploring the recesses under the cliffs at Noss, Shetland Islands (see text, page 102, and Color Plate II). The birds on the rock in the foreground are murres; those flying are kittiwakes.
