MarILa MARILA (Linné). 
SCAUP DUCK. 
A single male was seen on a small pond at Demarcation Point, on 
May 31, 1914. 
Several scaups of some kind were seen near Wrangel Narrows, _ 
southern Alaska, April 9, 1913. | 
CHARITONETTA ALBEOLA (Linné). yy 
BUFFLE-HEAD. 
A single specimen was seen in Cross Sound, Alaska, on April 13, 
1913. . 
HARELDA HYEMALIS (Linné). 
OLD-SQUAW. 
During the spring and summer of 1913 this species was seen in 
abundance about Bering Sea and the Arctic coast of Alaska. 
At St. Lawrence Island, on June 2, 1913, they were very common 
in pairs and small flocks. When paired the female very often flies 
ahead of the male as does the female eider. A set of six fresh eggs 
was taken at St. Lawrence Island, June 25, 1913. | 
At Humphrey Point, Mr. Dixon first saw Old-squaw on May 20; 
I did not note them at Demarcation Point until May 24. 
Although they were quite common during June I found no nests, 
but I am convinced that some must have bred near by. Mr. Dixon 
found them breeding at Humphrey Point. 
Throughout June the males could be found in every stage of 
plumage change. Two males taken on June 22, showed one in full 
summer plumage, and the other with the winter dress but little 
changed. 
From July 5 until I left Demarcation Point males were constantly 
arriving in small flocks from the east and collecting in Demarcation 
Bay where they were no doubt about to moult, for at Cross Island on 
July 27, 1913, we found many male Old-squaw unable to fly owing to 
moulted primaries.
