NORTH AMERICAN BIRDS. 



IS 



nesting sites, and each lays a single white egg upon the bare rock or ground in 

 crevices. On the Pur Seal Islands they also breed in great numbers, occupying the 

 cliffs with the other auks. They arrive in May and deposit their eggs deep down 

 in the crevices. The eggs taken on these islands are chalky white, and measure 

 2.31x1. 61 largest, and 2.06x1.50 smallest. 



19. WHISKEBED AUKLET. SymorliyncMs Pygnwus (Gmel.) Geog. Dist.— 

 Coasts and islands of the North Pacific, from Unalaska through the Aleutian chain 

 to Kamtschatka. 



From what is known of this species it appears that its general habits are simi- 

 lar to those of the Least Auklet, but It is far from being as common. Another name 

 by which it is known is Red-nosed Auk, the bill in adult birds being of a deep ver- 

 milion, tipped with bluish. A tuft of filamentous feathers on the head curves for- 

 ward so that it hangs directly over the bill. According to Nelson the species is un- 

 known from the Fur Seal Islands and we have no knowledge of its numbers and dis- 

 tribution in the Aleutian chain. It breeds abundantly on Near Islands, but it does 

 not winter there. It also breeds on the Commander Islands.
