i6th. On the latter day more California Murres were 

 found on the water than any time before during the sum- 

 mer. One flock numbered fully a score. Several young 

 of the year were seen. Each one was under the guard- 

 ianship of an adult. A male Pacific Fulmar of the dark 

 phase was taken on the water well toward the eastern 

 shore of the bay. Its plumage was bleached and worn, 

 and new feathers were beginning to appear. The testes 

 had apparently been dormant during the breeding season. 



Migratory movement on the 17th was limited chiefly 

 to the California Murre. Many were on the water, but 

 the greater number were pursuing their way south. One 

 flock of migrants had thirty in it. Four companies of 

 White-winged Scoters in high black plumage came into 

 the bay from the direction of Pt. Cypress during the fore- 

 noon. They were adjudged to be recent arrivals from 

 the breeding grounds, because their general mien and 

 their plumage was so entirely different from that of the 

 ragged and faded birds found not far out from the surf 

 along the sandy beaches earlier in the summer. In 1892 

 there was a similar appearance of these birds in high 

 ieather. 



Migration in the California Murre was greater on the 

 i8th than upon any previous day of the season. Not only 

 did they appear in quicker succession, but large wedge- 

 shaped flocks were numerous. A good many companies 

 were on the water, but these were insignificant in num- 

 bers compared with those winging their way southward. 

 There was no migration apparent in other species, except 

 in the Northern Phalarope and Dark-bodied Shearwater. 

 In both it was slight. 



20th. There was a heavy fog during the forenoon un- 

 til about eleven o'clock, when it lifted for awhile, settling 

 down again between twelve and one. After one o'clock
