ALEUTIAN SAVANNAH SPARROW 707 



and Miller confirmed the identification at the Museum of Vertebrate 

 Zoology in Berkclej'' as the race P. s. sandwichensis. 



Similarly Savannah sparrows occur at sea in the spring, G, D. 

 Hanna (1917) reports that on June 10, 1916, in the pack ice south of 

 St. Matthew Island, the largest of the Pribilof Islands, a Savannah 

 sparrow came aboard ship and stayed all day. 



Gabrielson and Jewett (1940) state tliat in the fall sandwichensis 

 appears in eastern Oregon by September 27 and stays until November 

 5 ; in the spring they first appear about March 24 and are present until 

 May 10. 



In the winter sandwichensis is found along the Pacific coast from 

 southwestern British Columbia south to central western California 

 and in the Great Valley of California. In California, at least, it 

 mingles with other races of Savannah sparrows, from which it can be 

 readily distinguished by its larger size (R. R. Tahnadge, pers. comm. 

 to Mr. Bent). 



The 1957 A.O.U. Check-List lists this race as casual in the Pribilof 

 Islands and east of the Cascade Mountains in Oregon. To this must 

 be added a record made by A. M. Bailey (1926), who collected an 

 adult female sandwichensis at Wainwright, Alaska, on Oct. 5, 1921. 

 This record certainly qualifies as a "casual," because Wainwright, on 

 the northern Alaskan coast far inside the Arctic Circle is nearly 1000 

 miles outside of its normal range, and at that date snow covered the 

 tundra and the ice was already 8 inches thick on the tundra ponds.
