Bay, where he collected a specimen. Apparently, Wetmore did 

 not observe them on Alaska Peninsula in 1911, and I did not 

 positively identify this jaeger at Izembek Bay in 1925. 



Turner (1886) says "The Long-tailed Jaeger is rarely seen 

 on the Eastern Aleutian Islands. I saw one on Sannakh Island in 

 July, 1878. I saw a few at Atkah Island in 1879, and two at 

 Attu Island in 1880 . . . This species is reported to breed at the 

 Semichi Islands." 



Friedmann (1934) reports a number of bones of this jaeger 

 found in middens on Amaknak Island. 



Stevenson obtained a specimen on Ilak Island, September 8, 

 1921. 



We observed it only once in the Aleutians. On June 13, 1937, 

 I watched a bird in the normal light-colored plumage, flying about 

 with three parasitic jaegers. 



Clark (1910) reports seeing one on Bower's Bank, Bering Sea. 



Hartert (1920) records two specimens from Commander Is- 

 lands. Stejneger (1885) stated that they do not nest there.

Though the glaucous gull normally nests north of the Aleutian 

 district, it reaches this area in considerable numbers in winter 

 and in migration to more southern localities. As Friedmann 

 suggested (1935), it is practically certain that Turner was in 

 error when he reported "countless thousands" of these gulls on 

 cliffs at Kodiak. Friedmann records several bones found in 

 middens on Kodiak, adding, "Macoun mentions a bird in the Hen- 

 shaw collection, and 3 eggs taken in June, 1880, now in the 

 Mailliard collection, [which] are the only other records I have 

 found." 



While these are recorded under the name Larus h. hyperboreus, 

 they could possibly refer to L. h. barrovianus. We do, however, 

 have at least one undoubted specimen of L. h. hyperboreus — a 

 male taken at Unalaska Island by Wetmore on June 9, 1911. 

 Though this specimen was listed by Oberholser (1918) under 

 L. h. barrovianus, examination of the speciman shows that it 

 has the massive beak that characterizes L. h. hyperboreus, the 

 measurements being greater than in barrovianus. Since it is
