292 SWIMMERS. 



Hutchins Goose is now considered a variety of ca?iadensis, 

 though in habits it is quite distinct. 



The present race breeds in the Arctic region and winters in the 

 Southern States : but on the Atlantic coast is now rather rare north 

 of Cape Hatteras, though formerly it was quite common. On the 

 prairies and west of the Rockies these birds are still abundant. 



Note. — The Cackling Goose {B. canadensis 7ninima), a 

 smaller race, — length about 24 inches, — which breeds in Alaska 

 and winters in California, is occasionally represented in the Mis- 

 sissippi valley by a few individuals. 



Another occasional visitor from the West to this faunal province 

 is the Black Braxt {B. nigricans'). A few examples of this 

 species have been taken on the Atlantic coast. 



Still another visitor of this group is the Barnacle Goose 

 {B. leiicopsis)., a European bird. This species is said to be a 

 regular visitor to South Greenland, and Reinhardt thought it 

 nested in the interior of that country. It has been seen also on 

 Hudson Bay.
