DISTRIBUTION 



Range. — In the Eastern Hemisphere: to the limit of trees from 

 Norway to western Siberia; in winter south to central France, north- 

 ern Italy, western Rumania, and central Russia. In America, from 

 Alaska and northern Canada to the central part of the United States. 



Breeding range. — The American races of the northern shrike breed 

 north to the limit of trees in northern Alaska (Lower Noatak River, 

 Kobuk Valley, and Seward Creek near Circle) ; central Yukon (Ogil- 

 vie Range) ; northern ISIackenzie (Fort McPherson, Fort Anderson, 

 Mc Vicar Bay on Great Bear Lake, and Fort Reliance) ; northern 

 Manitoba (Lac du Brochet and Cliurchill) ; and northern Quebec 

 (Chimo). East to northern Quebec (Chimo and Indian House 

 Lake) ; and Labrador (Lake Melville and the east coast). South 

 to Labrador (Lake Melville) ; central Quebec (possibly Anticosti 

 Island, Lake Abitibi) ; northern Ontario (Moose Factory and Fort 

 Severn, probably; casually to Ottawa and Toronto) ; central Sas-

 Landing) ; and southern Alaska (Homer, mouth of the Chulitna 

 River, and Nushagak). West to western Alaska (Nushagak, Kig- 

 luaik, and the Noatak River). 



Winter range. — The northern shrike probably winters occasionally 

 nearly as far north as it breeds but winter records from much of that 

 region are scarce. In the southern part of its winter range it is quite 

 irregular, and it is likely that its southward wanderings are in search 

 of food. Insofar as actual records go, this shrike winters north to 

 central Alaska (Flat, Toklat River, and Chilkat) ; central British 

 Columbia (Francois Lake and probably Thudade Lake) ; central 

 Alberta (Belvedere, Edmonton, and Camrose) ; central and south- 

 ern Saskatchewan (Cochin and Lake Johnstone) ; southern Manitoba 

 (Aweme, Lake St. Martin, and Hillside Beach, Lake Winnipeg) ; 

 central Quebec (Great Whale River, Quebec, and Bonavcnture Is- 

 land) ; and northern Newfoundland (Hare Bay) . East to Newfound- 

 land (Hare Bay, Salmonier, and Tompkins) ; Nova Scotia (Anti- 

 gonish and Bridgetown) ; New Brunswick (Grand Manan) ; the New
