young- were seen on the wing and the total number of adults did 

 not exceed (apparently) lOO birds. 



The Aleutian Tern is easily distinguished from the* Arctic Tern 

 in life. It appears larger and much darker, in some lights nearly 

 black. The white forehead is rarely visible unless the bird is flying 

 low and the light is strong. 



DIOMEDEA NIGRIPES 



Black-footed Albatross 



Common on the Pacific but not seen in Bering Sea. Among the 

 birds that followed the ship were some probably younger birds in 

 which the white about the base of the bill and upon the rump was 

 much restricted, or occasionally seemed to be wholly absent. Also 

 one or two were seen in which the white about the face was of 

 larger extent than usual. 



On the homeward voyage the species was more abundant than in 

 the spring. Nine birds were counted at one time and it was not until 

 within about 75 miles of Vancouver Island that the last one dis- 

 appeared. 



FULMARUS RODGERSI 

 Rodger's Fulmar 



Often abundant in rough weather, especially about the Seal 

 Islands, East Cape and other rocky cliffs in Bering Sea. A number 

 were seen in the Arctic Ocean some hundred and fifty miles north 

 of Cape Serdze, Siberia. 



As we pitched about in the rough weather the Fulmars came close 

 about the ship and often rested on the water like gulls. At such 

 times, as we rode high over the oncoming waves, one could look 

 down on the backs of a score or more of these birds calmly resting 

 in the trough of the sea with huge masses of swirling gray water 

 threatening to engulf them at every turn. In such positions I could 

 note every detail of their plumage. Many had the gray of the 

 mantle as extensive and unbroken as in glupischa. 



PUFFINUS GRISEUS 



Sooty Shearwater 



PUFFINUS TENUIROSTRIS 



Slender-billed Shearwater 

 I have already spoken of the thousands of. Sooty Shearwaters 

 in the North Pacific and about the Aleutian Islands. Among these
