The range as outlined is for the entire species, which is now 

 separated into four geographical races. The eastern crow (Corvus 

 brachyrhynchos brachyrhynchos) is found from Maryland, the northern 

 parts of the Gulf States, and northern Texas north to Newfoundland, 

 Quebec, northern Manitoba, and southwestern Mackenzie; the southern 

 crow (Corvus b. paulus) occupies the southeastern part of the range 

 (except Florida) west to eastern Texas; the Florida crow (Corvus b. 

 pascuus) is found only in the Florida Peninsula; the western crow 

 (Corvus b. hesperis) occupies the western part of the range north to 

 southern Saskatchewan and central British Columbia. 



Winter range. — Resident throughout the southern part of the breed- 

 ing range and north to southern British Columbia (Comox, Chilliwack, 

 and Okanagan Landing) ; southern Saskatchewan (East End) ; south- 

 ern Manitoba (Portage la Prairie) ; southern Ontario (Sault Ste. 

 Marie, North Bay, and Ottawa) ; northern Vermont (St. Johnsbury) ; 

 Maine (Avon and Ellsworth) ; New Brunswick (Scotch Lake and 

 Fredericton) ; Nova Scotia (Wolfville and Pictou) ; and southeastern 

 Newfoundland (St. John's). 



Migration. — Since in winter the c.row is found in limited numbers, 

 as far north as southern Canada, dates of arrival and departure do not 

 convey a true picture of its migrations. Extensive migratory flight is, 

 in fact, confined to the birds of the Great Plains region. In the files 

 of the Fish and Wildlife Service there are several hundred instances of 

 crows banded during the summer in Saskatchewan that were subse- 

 quently recovered during the following fall and winter at well-connected 

 series of localities south through North and South Dakota, Nebraska, 

 Kansas, Oklahoma, and Texas. Similarly, crows banded during winter 

 in Oklahoma and Kansas were recovered during the following spring 

 and summer north through Nebraska and the Dakotas, to Manitoba, 

 Saskatc.hewan, and Alberta. Crows banded at northern points on the 

 Atlantic coast show very little movement but are generally recovered 

 within 100 miles of the point of banding.
