ARCTIC FOX, Alopex lagopus 



(Tigannek, Kaynroktoruk) 



pri bi lof^nsis 



Range. — Circumpolar, largely above the Brooks 

 Range and beyond the limit of trees. 



Habitat. — Primarily along the marine coasts, on 

 open tundra or rocky beaches; in winter goes out 

 long distances on sea ice: occasionally consider- 

 able distances inland. 



Races in Ala-ika. — The mainland race is innuitus 

 (type locality: Karogar River, Point Barrow). 

 Two island species have been described, but are 

 now' regarded as subspecies: hallensi-s (type local- 

 ity : Hall Island, Bering Sea) occurs on Hall, St. 

 Lawrence, and St. Matthew Islands; pribilofemis 

 (type locality: St. George Island) occurs on the 

 Pribilof Islands and most of the Aleutian Islands 

 west of Unalaska. 



Introductions. — Since the days of the Russians, 

 in the mid 18th century, blue foxes have been 

 transplanted to the Pribilofs, most of the Aleu- 

 tians, and many other islands, often to the detri- 

 ment of native species.
