Cerorhinca monocerata: Rhinoceros Auklet 



Bent (1919) gives the breeding range of this species as "west 

 to the Aleutian Islands (Atka, Agattu, and Umnak Islands)." 

 We found no trace of this bird on any of our expeditions. Fried- 

 mann (1935) records two specimens taken at Kodiak Island in 

 1842 or 1843 by Wosnessensky, and he mentions that they were 

 observed there by Brandt. He has also recorded three humeri 

 from middens on Little Kiska Island (1937). 



Austin H. Clark (1910) said: "This species was observed in 

 limited numbers at Atka and at Agattu, and in the northern 

 Kurils I occasionally noticed small companies on the water as 

 far south as Simushir." 



Cahalane (1943) reported: "I observed a number of these 

 auklets on October 4 between Amalik and Katmai Bays." This 

 observation was made in 1940. 



Hartert (1920) wrote of the Commander Islands: "Cerorhinca 

 monocerata was obtained by Grebinitzki, but neither Stejneger 

 nor Sokolnikoff came across it." 



Fratercula corniculata: Horned Puffin 



Attu: Ka-gee-ach 

 Atka: Ka-geeth'-ali 



Russian, Commander Islands: Ipatka, (pronounced Ipatok on Copper Is- 

 land) Stejneger 



The horned puffin is so universally distributed and so common 

 that it is hardly of interest to single out a particular locality. As 

 Bent (1919) has aptly stated it : 



The horned puffin is essentially an Alaskan and a Bering Sea bird, being 

 found breeding throughout the whole length of the Alaskan coast, from 

 Cape Lisburne, north of the Arctic Circle, south nearly to British Columbia; 

 it also breeds westward throughout the Aleutian Islands and on all the 

 coasts and islands of Bering Sea. 



It also breeds on the Commander Islands and the Siberian coast. 

 We found the horned puffin on all suitable islands, from Kodiak 

 to Attu, including the Shumagins and Sanak; Gabrielson found 

 them in the Semidis. The only factor that limits their distribu- 

 tion is unsuitable terrain. Naturally, they do not nest on the low 

 shores of the north side of Alaska Peninsula, but they do nest on 

 nearby rocky Amak Island. There were at least a few at nearly 

 every island of the Aleutian chain.
