 Aethia pusilla (Pallas). 



LEAST AUKLET. 



This is the most abundant bird of northern Bering Sea. We found 

 them in enormous numbers at St. Lawrence Island, Providence Bay, 

 East Cape, and Big Diomede Island. At the latter place on June 15, 

 1913, there were literally swarms of Least Auklets; the air was full 

 of them, the rocks covered with them, and judging from the noise 

 every hole and crack in the rocks contained one or more. They go 

 further inland from the cliffs here than either the Crested or Paroquet 

 Auklets. 



They make a considerable variety of noises, the least common of 

 which is a note suggesting the call note of a Red-winged Blackbird. 

 I have heard them utter it while on the wing on the breeding ground. 



A large series of specimens was taken at St. Lawrence Island, East 

 Cape, and Big Diomede Island. Specimens from Copper Island and 

 Bering Island were purchased including a female taken July 19, 1910, at 

 Bering Island. 



Phaleris psittacula (Pallas). 



PAROQUET AUKLET. 



Observed wherever the two preceding species were noted but by 

 far the least common of the three. 



Specimens were taken at East Cape, Siberia. A male taken at 

 Copper Island, July 24 was purchased. 



This species is much tamer than the Crested Auklet. 



LUNDA CIRRHATA (Pallas). 

 TUFTED PUFFIN. 



The collection contains specimens from Cape Shipunski, East Cape, 

 Copper Island, and Bering Island. 



Fratercula corniculata (Naumann). 



HORNED PUFFIN. 



We found this an abundant species at all the suitable localities 

 visited in northern Bering Sea. Specimens were secured at East Cape.
