LOGGERHEAD SHRIKE 



The Loggerhead Shrike (Lanius ludovicianus) as a species occupies prac- 

 tically all of the United States and Mexico and southern Canada. It separates, 

 however, into six subspecies, all but one of which occur in North America. 

 This one, the Mexican Shrike {Lanius ludovicianus mexicanus) is confined to 

 Mexico. The distribution of the North American forms is as follows: 



The Southern Loggerhead Shrike {Lanius ludovicianus ludovicianus) is 

 resident in the southeastern United States and breeds north to eastern North 

 Carolina, northern South Carolina, central Georgia, central Alabama, central 

 Mississippi, and northern Louisiana; west to Louisiana; and south to the coast 

 of the Gulf of Mexico and to Florida. 



The Migrant Shrike {Lanius ludovicianus migrans) breeds in the north- 

 eastern United States and southeastern Canada, north to New Brunswick, 

 Prince Edward Island, southern Quebec, southern Ontario, Michigan, Wiscon- 

 sin, and Minnesota; west to Iowa, eastern Kansas, and eastern Oklahoma; south 

 to Arkansas, western Tennessee, Kentucky, western North Carolina, and 

 southern Virginia; and east to Virginia, Maine, and New Brunswick. It winters 

 south to the Gulf States, west to Texas. 



The White-rumped Shrike {Lanius ludovicianus excubitorides) breeds in 

 central western North America, north to southern Manitoba, central Saskatche- 

 wan, and central Alberta; west to Alberta, Montana, southeastern Oregon, 

 Nevada, northeastern and southeastern California; south to Tepic and Durango 

 in Mexico, and east to central Texas, central Oklahoma, central Kansas, North 

 Dakota, and South Dakota. It winters south over all Mexico to the Isthmus 

 of Tehuantepec in the state of Oaxaca. 



The California Shrike {Lanius ludovicianus gambeli) breeds in the Pacific 

 Coast region, north to southern British Columbia; south to northern Lower 

 California; and east to central eastern California, central Oregon, and Wash- 

 ington. It winters south to southern Lower California and through western 

 Mexico to the state of Morelos. 



The Island Shrike {Lanius ludovicianus anthonyi) is resident on the Santa 

 Barbara Islands in CaHfornia and on Santa Margarita Island, Lower California. 



Only three of these subspecies are migratory, and these three in spring, 

 autumn, and winter become so intermingled with other races or with each 

 other that it is often difficult to separate their migration notes. In the follow- 

 ing tabular arrangement records of the White-rumped Shrike are marked with 

 an asterisk (*) ; those of the California Shrike with a dagger (f) ; and all the 

 others refer to the Migrant Shrike.
