Marila marila (Linne). 



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. 



Charitoxetta albeola (Linne). 



BUFFLE-HEAD. 



A single specimen was seen in Cross Sound, Alaska, on April 13, 

 1913. 



Harelda hyemalis (Linne). 



OLD-SQUAW. 



During the spring and summer of 1913 this species was seen in 

 abundance aVjout 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 wintef 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.
