96 THE CONDOR VoL. XI a flock of sea-pigeons, while I continued along the rocky back-bone to the extreme western point, but without finding any occupied nests and encountering but few birds. The day of the Pedro Rookery was past! The birds had dwindled in num- bers so they could be actually counted, and what a meager list the colony gave! 1. Phalacrocorax 15elag?icus res151endens (Baird Cormorant) 24 2. Phalacrocorax penicillalus (Brantit Cormorant) 24 3. Uria lroile cahfornica (California Murre) 20 4. Pelecanus californicus (California Brown Pelican) 14 5. Cepphus columba (Pigeon Guillemot) 15 6. Larus occidenlalis (Western Gull) 10 7. Lunda cirrhala (Tufted Puffin) 6 8. Larus heermanni (Heermann Gull) 6 While we were dwelling on this serious decrease in Pedro bird statistics, Snow at the foot of the bluff was, from all appearances, making serious inroads on the supply of eatables, and from a distance we could hear, between the roar of the bat- tering waves, the cry of our angry boatman whose idea of two hours and ours materially differed. The reader will acknowledge, with this situation before us, it would have been unwise to extend our investigations further. After "sliding" down the bluff and taking a hurried lunch, we joined our impatient boatman who told direful tales of what might have happened had we delayed our coming any longer. With the stiff breeze that had come up, he declared, it would have been impossible for him to take us off and we would have been left on the isle with our scanty supply of provisions. But even the boatman did not know how grave a matter this would have been; for he could scarce dream what lusty appetites were possest by our commissariat and official photographer. Ornithologically and oologically considered our trip was a failure, and photo- graphically partly so. Newcomers to the isle will no doubt find fewer birds than were noted by our party, for now, with the coming of the railroad and the attendant population along its line, the number of feathered dwellers on these sea-rocks will be less than ever. San Francisco, Cahfornia. AN ORNITHOLOGICAL TRIP TO LOS CORONADOS ISLANDS, MEXICO By HOWARD W. WRIGHT WITH THREE PHOTOS BY THE AUTHOR N June 20, 1908, with three friends, Mr. J. R. Maclintock, Mr. Frank H. Long and Henry Wetherby, I left San Pedro for Los Coronados Islands, Mexico. It was the longest trip I had ever taken in my sail boat, the "Sea Bird", which is about thirty feet over all. The trip down was uneventful save for a sixteen-hour calm, during which the swells were rolling mountain high, and which caused a falling off of appetite on the part of my friends, to say nothing of myself. Finally a brisk, stern wind sprang up, and we started at a rapid pace for San Diego, making before dark about eighty miles. All spirits rose with the rising of the wind and on Sunday night, the 21st, we
