storms, some dry vegetation always seemed to be exposed. The 

 Rosy Finch flocks varied from 6 to about 30 individuals." 



In 1937, the first family of young on the wing was seen on 

 Buldir Island on June 18, and another such family was seen on 

 Little Kiska Island on June 22. 



Two other forms are of interest here. Leucosticte tephrocotis 

 umbrina, from the Pribilof Islands (Murie 1944, p. 122), has 

 become differentiated as a darker bird, about the same size as 

 griseonucha, and L. t. maxima, the Commander Islands rosy finch, 

 is the largest of the group. The bird of the Commander Islands 

 is of the American type ; the nearest Siberian form, brunneinucha, 

 from Kamchatka, is of an entirely different group. Thus, the 

 rosy finches show a gradual increase in size north and west 

 through the Aleutian district — culminating in the largest one 

 being found on the Commander Islands (which is the farthest 

 point reached to the west), and the darkest one being found on 

 the Pribilof Islands.

Osgood (1904) observed flocks of these birds at Nushagak and 

 lower Nushagak River in September, and they were common at 

 Becharof Lake, Kanatak, and Cold Bay during October. McKay 

 and Johnson have collected specimens in breeding plumage in 

 June and July at Nushagak, and Cahalane (1943) reports a 

 group near the outlet of Katmai River on October 4, 1940. 



We did not see this bird. Wetmore, however, according to his 

 field notes for 1911, heard a redpoll in the mountains west of 

 Morzhovoi Bay on July 26, and he suspected that it may have 

 been this species. He felt certain that it was not A. f. flammea. 



Stejneger (1885) lists this redpoll as a winter visitor in the 

 Commander Islands. 



Acanthis flammea: Common Redpoll 

 Acanthis flammea flammea 



Osgood (1904) found this redpoll to be common about Lake 

 Iliamna and Lake Clark and the Chulitna River. McKay and 

 Johnson have taken specimens at Nushagak, and Hine (1919) 

 obtained specimens at Katmai Bay, where they began to appear 

 about the middle of July. Gabrielson found several on the Kvichak 

 River on July 23, and they were common at Iliamna Lake on 

 July 24. We observed these birds at Snag Point, Nushagak River,
