DISTRIBUTION 



Range. — The duck hawk is cosmopolitan in its distribution, the 

 breeding ranges of the northern subspecies being circumpolar and the 

 winter ranges extending south to the Indian Peninsula, Africa, and 

 southern South America, while other races occur in Malaysia and 

 Australia. The typical race, or Old World peregrine falcon (f'alco 

 peregrinus peregrinus), is doubtfully casual in Greenland (see discus- 

 sion by Jourdain, p. 42). The following account includes the duck 

 hawk and Peale's falcon (F. p. pealei), which is confined to the North 

 Pacific coast from the Commander and Aleutian Islands south rarely 

 to southern California (San Diego and Pacific Grove).

 north to Alaska (Nome, Colville River, Camden Bay, Barter Island, 

 and Demarcation Point) ; Mackenzie (Lockhart River, Melville Moun- 

 tains, and probably Bernard Harbor) ; Keewatin (probably Fullerton 

 and Repulse Bay); Franklin (Frozen Strait, Southampton Island, 

 Baffin Island, and Greater Kingwah Fiord); and Greenland (Holstein-
