LIFE HISTOKIES OP NORTH AMBEICAN DmNG BIEDS. 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 Eocks), 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 FaraUone 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.
