LIFE HISTORIES OF NORTH AMERICAN DIVING BIRDS, 189 
Fall—Mr. Bryant (1888) says that the murres begin to leave the 
Farallones “about the middle of September; by the first of October 
they have all left the island but can be seen upon the water.” Mr. 
Loomis (1895) noted a decided:migration of this species at Monterey, 
on August 17 and 18, 1894; on the 17th he noted that— 
Many were on the water, but the greater number were pursuing their way 
south. One flock of migrants had 30 in it. Migration in the California murre 
was greater on the 18th 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 insig- 
nificant in numbers compared with those winging their way southward. 
Winter—The California murres spend the winter in large num- 
bers off the coast of California and many of them return to the Far- 
allone Islands or their vicinity in December, although perhaps these 
are birds from farther north. There is a specimen in the United 
States National Museum collected at the Pribilof Islands on January 
29, 1874, which shows that at least a few birds winter as far north as 
Bering Sea. 
DISTRIBUTION. 
Breeding range.—Coast and islands of the North Pacific and Ber- 
ing Sea. From California (San Miguel Island, Farallones, and one 
or two points on the coast), Oregon (Three Arch Rocks), Washing- 
ton (coast islands), British Columbia and coast of southern Alaska 
(Forrester Island and St. Lazaria Island) westward throughout the 
Aleutian Islands and Commander Islands to Kamtschatka. In 
Bering Sea it breeds north to the Pribilofs and on St. Matthew 
Island. Herald Island and Wrangel Island records apparently re- 
fer to arra. 
Winter range-—Throughout the North Pacific from the Aleutian 
and Commander Islands to California (Newport Beach, Orange 
County). One taken at the Pribilof Islands January 29 and others 
seen February 4. 
Spring migration.—Arrive at the Farallone Islands April 1. 
Fall migration.—Birds leave their breeding places on the Faral- 
lones from September 15 to October, and migrants passed Monterey 
commonly August 17 and 18. 
Egg dates.—Farallone Islands: 110 records, March 6 to July 25; 
55 records, June 13 to July 4. Bering Sea: 6 records, July 3 to 22; 3 
records, July 7 to 18. Southern Alaska: 3 records, June 20, July
