2iDZ Hanna, New Birds for the Pribilofs. [April 



native hunters. They did not recognize them as belonging to a separate 

 species from the pacific and king eiders with which they were associated, 

 and since the natives must be depended upon by the collector to a large 

 extent for sea ducks it is likely the birds come more frequently than has 

 been suspected. It would seem natural for individuals to pass in the 

 vicinity of the Pribilofs each year because they have been reported in 

 winter as far south as the Aleutian Islands. One of the birds collected 

 was preserved in formalin for anatomical study. 



Melanitta deglandi dixoni (Brooks). Western White-winged 

 Scoter. — Four specimens of the Western White-winged Scoter have been 

 taken on the Pribilofs during the last three years. All were females but 

 this was merely an accidental circumstance because males have been seen. 

 The first specimen was secured on October 30, 1916, at St. George Island 

 by the writer. The next was taken on November 15, 1916, at the same 

 island by Dr. H. P. Adams, formerly physician of the U. S. Bureau of 

 Fisheries. Another was secured at St. George Island on February 4, 1917, 

 and one at St. Paul Island, February 8, 1918, both by the writer. 



The species is of regular occurence about the islands in winter. It has 

 been seen on several occasions before any specimens were secured but 

 was not recorded because positive specific identification could not be 

 made. The natives recognize the bird as belonging to a different species 

 from the eiders with which it comes and associates. The birds feed along 

 shore just outside of the surf line in small flocks. The white speculum 

 of the wing makes them excellent targets for the man with the shot gun 

 out after fresh meat in the dim light of the arctic winter morning. 



Aristonetta valisineria (Wilson). Canvas-back. — A beautiful male 

 Canvas-back was taken on St. George Island on May 18, 1917. The 

 Pochard, which is difficult for the average hunter to distinguish from this, 

 has been taken on the island but once so both species must be considered 

 as rare visitors. However the natives are inclined to call all ducks "Mal- 

 lards," when the females have a general resemblance to that species and 

 the males are brightly colored. Thus Pin-tails, Buffle-heads, Golden- 

 eyes, and other river ducks are very apt to be reported as Mallards unless 

 the collector makes a personal examination of each bird secured. Pro- 

 bably the inability to identify the ducks has prevented the securing of 

 many desirable specimens here in the past and delayed the reporting of 

 others until recently. 



Clangula clangula americana Bonaparte. American Golden-eye. 

 Two specimens which clearly belong to this subspecies were collected; a 

 male on St. George Island, May 6, 1917; and a female on St. Paul Island 

 January 31, 1918. From a study of female specimens collected in the fall 

 of 1913, it is certain that there is a mingling of the European and Ameri- 

 can forms in the vicinity of the Pribilofs.

 male and female European Teal on St. Paul Island, May 4, 1918, a per-
