breaking through one is immediately in very deep water. Masses of this dead vegetation had broken away from the edges, and were floating about the surfaces of the water, and on nearly all of them one could, with the glasses, distinguish eggs lying right on the surface of the débris, without any attempt at nests. I only saw two clutches with three eggs, the rest of the nests I could see having only one egg in them. July 16th–21st. I only saw old birds on the part of the beach that I visited.
Herring-Gull (L. argentatus), Lesser Black-backed Gull (L. fuscus), Great Black-backed Gull (L. marinas).—There were numbers of these three species on the beach in both mature and immature plumage. They seemed to make a special haunt of the pools where the Black-headed Gulls breed.
Guillemot (Uria troile).—I picked up a dried specimen of this bird amongst the debris on the beach.
Little Grebe (Podicipes fluviatilis).—May 10th-14th. Breeding in considerable numbers in the ditches and pieces of water on the marsh-land. I found nests with fresh eggs and eggs just hatching out on May 13th.
