LEUCOSTICTE TEPHROCOTIS GRISEONUCHA (Brandt). 

 ALEUTIAN LEUCOSTICTE. PETUSCHOK. 



The Aleutian Leucosticte was common on the Aleutian Islands we 

 visited, and also on Copper and Bering islands. At Unalaska and 

 Atka it was most frequent at moderate elevations, about patches of 

 snow, only one or two being seen in the valleys. At Attn and on 

 the Commander Islands I found it most commonly along the sea- 

 coast, especially about rocky beaches. At Attn I found a pair about 

 some cliffs just behind a narrow beach, whose actions led me to sus- 

 pect that they had a nest in the vicinity, but 1 was unable to find it. 

 1 did not find this species on Agattu. 



Measurements of a series of 28 specimens from Unalaska, Atka, 

 Adak, Kiska, Attn, and from Copper and Bering islands, show 

 a tendency to an increase in size toward the west, which is correlated 

 with a slight increase in intensity of coloration, the Unalaska birds 

 averaging smaller and duller, and the Commander Island birds 

 larger and brighter, the others being intermediate. 



CHLORIS SINICA USSURIANUS Hartert. 

 USSURILAND GREENFINCH. 



The Ussuriland Greenfinch was very common on Matsushima, in 

 the Sea, of Japan, where it frequented hillsides covered with scrubby 

 bushes. In habits it appeared to be similar to the common Gold- 

 finch (Carduelis carduelis). 



PASSERINA NIVALIS TOWNSENDI Ridgway. 

 TOWNSEND'S SNOW BUNTING. SNIEGIROK. 



Townsend's Snowflake is a common bird on all the Aleutian and 

 on the Commander islands. It is usually very wary, and speci- 

 mens are hard to secure. At Unalaska, I found the Snowllakes 

 common only in the higher altitudes, where the ground was largely 

 covered with snow . They were here extremely shy, and I only suc- 

 ceeded in getting four. At Atka also they were only found in the 

 higher elevations where the ground was mainly snow covered, and 

 1 had great difficulty in obtaining specimens, more than in shooting 

 ptarmigan. I did not find this species on Agattu; but I was unable 

 to visit the more snowy districts of the island. On Attn and on the 

 Commander Islands this bird was most c< mmon along the seacoast, 

 especially about rocky beaches, where it was not at all dillicult to 

 get within range. At Attn, indeed, 1 saw none at all in the snowy 

 districts. 



As in the case of the other resident finches of the Aleutian Islands, 

 birds from Unalaska, average the smallest, the average size gradually 

 increasing, reaching a maximum on the Commander Islands.
