THE BIRDS OP THE PRIBILOF ISLANDS. 361 



of his assistants, to examine them for this paper, and the results are given under the 

 species with Mr. Judd's initials attached. A few were examined by myself on the 

 islands, in which cases my own initials follow. Mr. Judd speaks as follows of his 

 examination : 



The birds, principally sparrows and shore birds, collected by Mr. W. Palmer on the Pribilof 

 Islands during the summer of 1890, had lived for the most part upon insects, although moUusks, seeds, 

 and berries had occasionally been resorted to. The food of these birds is very different from that of 

 birds along the eastern coast of the United States in that it consists in its greater part of flies. Some 

 beetles were eaten, but not to nearly such an extent as would have been commonly expected. Little 

 pieces of red and black porous lava were found among the mineral matter contained in the stomachs, 

 plainly indicating the volcanic origin of the collecting ground. Of the 32 stomachs examined, 6 were 

 Pacific godwits ; one of these contained hundreds of specimens of an exceedingly rare beetle. 



The chilly damp nights are doubtless responsible for much of the fly food.
