26 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 56 



RISSA TRIDACTYLA POLLICARIS 



Pacific Kittiwake 



This seems to be the commonest gull in Bering Sea. We saw a 

 few breeding on the cliffs at St. Paul Island ; they were quite common 

 on Walrus Island and a few were nesting on the high cliffs on St. 

 Matthew Island. At Walrus Island, where there are no high cliffs, 

 we had an unusually good opportunity to examine their nests, which 

 were placed on little shelves on the faces of perpendicular rocks in 

 little groups of from four to six pairs each, often close to the Murres 

 or Red-faced Cormorants. The nests were neatly made of soft green 

 grasses, securely plastered onto the rocks, and contained one or two 

 eggs. 



RISSA BREVIROSTRIS 

 Red-legged Kittiwake 



Only one specimen of this beautiful species was taken, between 

 Bogoslof and the Pribilof islands. Several were seen about the 

 latter and could be distinguished by their darker mantles, short bills, 

 less black on their wing tips and by their bright red feet. We did 

 not see their breeding grounds. 



LARUS HYPERBOREUS 



Glaucous Gull 



In the large breeding colony of Gulls on W' alrus Island there were 

 certainly a number of Glaucous Gulls, but just what the proportions 

 were of this and the following species we were unable to determine 

 as we were not allowed to do any shooting here. Only a few nests 

 still contained eggs, as most of the young Gulls were running about 

 and hiding under the tufts of grass which covered the highest part 

 of the island. 



LARUS GLAUCESCENS 

 Glaucous-winged Gull 



I assvnned that the majority of the Gulls breeding on Walrus Island 

 were of this species, but I have no reason for the assumption except 

 that this seems to be the commoner species. It is to be regretted that 

 we were unable to shoot any, although photography gave us plenty 

 to do during the half day spent on this fascinating little island. 



STERNA PARADISJEA 



Arctic Tern 

 A few Terns were seen in the northeastern part of Bering Sea, 

 undoubtedly of this species, which was the bird found at Nome.
