40. June 25, 1911. S. E. Farallon D., Calif. Warm; more or less foggy; little wind. I spent the day on the east end near the wireless and fog signal stations. Barpodacus melicanus. Ten or a dozen in cypress trees near fog station. Saw only one red-headed male. Shot one young-of-the-year. Salpinctes obsoletus. Common. Many young-of- the-year. Adults singing. Cairus occidentalis. Quite a number along shore and flying. Saw two brown-plumaged immature birds. Lunda currata. A few flying. Uria troile. A few flying. I have noticed large bands of this species and the next on the water offshore every day. Pseuduridia columba. Quite a number flying and sitting about the shores and on the rocks high up on the hillside where the tower is located. Found a bird on nest with one egg in rock pile in level ground near fog station... There may have been a young bird also that we did not see for later, the mate of the nest bird flew about for an hour or so with a small fish in its bill. The nest bird also left and flew with it part of the time. They both appeared very solicitous and anxious to get back to the nest while we were working in the vicinity for petrels. The nest bird sat very close and did not attempt to escape. Nest more after style of anklelets in location than like pigeon guilberts,'
