BROOKS: BIRDS FROM EAST SIBERIA AND ARCTIC ALASKA. 395 
POLYSTICTA STELLERI (Pallas). 
STELLAR’S EIDER. 
A few Stellar’s Eiders were seen at Cape Shipunski, May 23, 1913, 
At Providence Bay they were quite common in flocks during the first 
three weeks of June 1913, and at East Cape, on June 7. On the 
south side of St. Lawrence Island a number of large flocks were about 
on June 25, 1913. These flocks consisted mostly of males, and the 
birds keeping in shallow water close to the beach were so massed that 
no space of water could be seen between them. We found no nests, but 
had little time at our disposal to devote to this branch of field work. 
At Humphrey Point Mr. Dixon found a number of these birds, and 
secured a good series between June 12 and July 7. At Demarcation 
Point I saw on June 8, 1915, only one bird, a female sitting on the 
bank of a small pond in company with a pair of Old-squaw. 
‘  ARCTONETTA FISCHERI (Brandt). 
SPECTACLED EIDER. 
This species was only observed at St. Lawrence Island, and Hum- 
phrey Point. On the south side at the former locality three specimens 
were taken from a small flock on June 25, 1913. 
At Humphrey Point, Mr. Dixon secured five on June 12 and 26, 
1914. 
SOMATERIA SPECTABILIS (Linné). 
KING EIDER. 
King Eiders were common about Cape Chibukak, St. Lawrence 
Island, in pairs and small flocks, on June 2, 1913. They were quite 
common at Providence Bay early in June, and a few were seen at East 
Cape, on June 7, 1913. 
At Cape Serdze enormous flocks were flying east, on July 16, 1913. 
Mr. Dixon found this species breeding sparingly at Humphrey 
Point where it arrived on May 15, 1914. 
[| found no nests at Demarcation Point nor did I see a bird until 
June 7. From this date I saw King Eiders about every other day but 
very sparingly and never paired; generally a male with three or four 
females or vice versa.
