FAUNA OF THE ALEUTIAN ISLANDS AND ALASKA PENINSULA 165 



Friedmann (1934) reports two bones from middens on Amak- 

 nak Island, and (1937) a bone from Dutch Harbor middens, a 

 skull and a femur from Little Kiska, and two skulls from Attu. 

 Undoubtedly these were not subspecifically determined. In 1937, 

 in the dirt foundation of a bald eagle's nest on Amchitka Island, 

 I obtained two humeri that appeared large enough to be a glaucous 

 gull. This identification was later supported by Friedmann, who 

 thought the bones were slightly undersized (which would indicate 

 barrovianus.) 



Bishop (1900) reported seeing several of this species at Una- 

 laska October 4, 1899. 



Another specimen collected at False Pass by Donald Steven- 

 son, April 28, 1925, is an immature bird typical of barrovianus. 

 Still another, similar to the above, was taken on Unimak Island 

 by F. L. Beals, April 5, 1941, and another one at Unalaska, 

 March 5, 1942. 



Cahn (1947), under heading of Larus hyperboreus, reports 

 seeing a few at Unalaska, and Taber ( 1946) reports a few winter- 

 ing at Adak. It would be difficult to determine the subspecies- 

 without specimens, but Sutton and Wilson (1946) observed im- 

 mature glaucous gulls wintering at Attu. On March 17, when 

 they made a count, there was a glaucous gull for every 25 

 glaucous-winged gulls. It is significant that they noted that the 

 size was similar to that of glaucous-winged gulls, suggesting bar- 

 rovianus. 



We did not find nesting birds of this species on either Una- 

 laska or Amak Islands, therefore it is surprising to recall that 

 Oberholser had listed his two specimens as "nestlings." 



Larus glaucescens: Glaucous-winged Gull 



Attu: Hlu-ka 



Chd-larch, immature 

 Atka : Shlil-ka 



Sliikax (Jochelson) 



Chid-li-arch, immature 



Cuh'igidax, immature (Jochelson) 

 Russian, Commander Islands: Tschaika, gull in general (Stejneger) 



The Aleut names given the glaucous-winged gull are obviously 

 the same in both dialects and resemble the Russian. 



This is the common breeding gull throughout the length of 

 Alaska Peninsula, the Aleutians, and other islands, including the 

 Kodiak-Afognak group. Osgood (1904) reported them nesting 

 on islands in Iliamna Lake and at Becharof Lake, and he observed 

 them at Nushagak. On July 24 and 27, 1940, Gabrielson found
