FAUNA OF THE ALEUTIAN ISLANDS AND ALASKA PENINSULA 187 



of adianta, therefore at present we may call this species, which 

 breeds on the Alaska Peninsula and on the Aleutian chain as 

 far as Umnak, C. c. columba. The race that is breeding on the 

 more western Aleutian Islands and the Commander Islands is 

 probably kaiurka, as indicated by Storer. 



In 1941, at Unimak Island, Beals and Longworth noted 4 birds 

 in winter plumage, and 5 in summer plumage on March 26; a 

 group of 15 birds in summer plumage was seen on April 8; and 

 8 in mottled plumage were noted on April 21. 



Brachyramphus marmoratum: Marbled Murrelet 



Brachyramphus marmoratum marmoratum 



On our expeditions we observed this bird frequently in south- 

 eastern Alaska, where it is common. On May 6, 1936, a bird in 

 the black and white plumage was seen at Port Chatham, Kenai 

 Peninsula; on May 11, at least 6 were seen between the Barren 

 Islands and Af ognak ( 1 of these birds was in the black and white 

 plumage) ; and on May 14, one or two birds (believed to be of 

 this species) were seen south of Alaska Peninsula and southwest 

 of Sutwik Island. Other murreiets were seen, but under circum- 

 stances unfavorable for identification. 



Marbled murreiets occur at Kodiak, as shown by Friedmann's 

 well-documented account, and may nest there. Osgood (1904) 

 says "Several murreiets (apparently this species) were seen on 

 Kanatak Bay October 13. A single immature specimen (No. 

 106605 U.S.N.M.) was taken near Nushagak by J. W. Johnson, 

 Sept. 5, 1885." 



Cahalane reports (1944) "I saw these birds commonly along 

 the Shelikof Strait coast, from Katmai Bay northward. They 

 seemed to be most abundant in Kukak and Hallo Bays." 



On July 27, 1940, Gabrielson observed a number of marbled 

 murreiets at the upper end of Iliamna Lake. 



Gianini (1917) reports seeing this species at Stepovak Bay. 



In 1925, I observed murreiets on both sides of Alaska Penin- 

 sula, near the western end, but positive identification was diffi- 

 cult. The marbled murrelet was most abundant on the south 

 side, between Ikatan Peninsula and Amagat Island, where several 

 pairs were taken. 



The species has been recorded frequently from Unalaska. Nel- 

 son (1887) found it there in May 1877 and says that it breeds 

 there. Bailey (1925) reports a specimen taken there by Hendee 

 on September 24, 1922, and Clark (1910) secured a female at 

 Dutch Harbor. Laing (1925) obtained a "breeding female with
