The nth was one of the rare days when there was no 

 fog, when the shore-Hne could be seen for miles. The 

 sea too was calm. It was a day of great migration in 

 Dark-bodied Shearwaters. They were passing Pt. Pinos 

 all the forenoon about three miles off shore. The eye 

 could follow them a long way as they came down the 

 coast and disappeared to the southward. There were 

 two almost continuous streams of them made up of strag- 

 gling companies and loose flocks. At nine o'clock and 

 again at eleven some of the latter were of such large size 

 the two streams became merged into a single broad one 

 at least an eighth of a mile in width. One of these flocks 

 was estimated to be two miles in length. Leadership ap- 

 peared to be exercised among them, for one of the birds, 

 apparently seeing I was making havoc with my gun in a 

 flock just in advance, left the flock he was in and flew 

 back along the advancing column, and as he passed by 

 the birds sheared off to the seaward, going past the boat 

 out of range. The whole manoeuvre was so obvious that 

 my boatman, who had also been intently watching it, un- 

 consciously to me, exclaimed, " that bird must be some 

 sort of a general." 



An adult Pacific Fulmar of the dark phase was shot as 

 it was resting upon the water. It had apparently dropped 

 out of the ranks of the Dark-bodied Shearwaters, for I 

 had been over the spot where it was taken only an hour 

 before and it was not there then. Its plumage was greatly 

 worn, and its ovary had no appearance of recent func- 

 tional enlargement. There was a good deal of migra- 

 tion in the California Murre and some in the Marbled 

 Murrelet, but only one or two companies of Northern 

 Phalaropes were seen. 



13th. During the morning there was a low fog hang- 

 ing over the bay and ocean. It seemed to arrest migra-
