COUES ON BIRDS OF DAKOTA AND MONTANA 



649 



The other species of Swan, (7. americanus, was not recognized, though 

 it doubtless occurs during the migration. 



The same remark applies to a species of Goose, Anser albifrons gam- 

 hell. 



ANSER HYrERBOREUS, Pall. 



Snow Goose; WniTE Brant. 



Abundant during the migrations. On a former occasion, I noted their 

 spring migration in Southern Dakota, at Fort Randall, from the latter 

 part of March through most of April. In the fall, I saw none until 

 October. 



BRANTA CANADEi^^SIS, (Linn.) Gray. 



Canada Goose. 



Whilst steaming up the Missouri in June, 1874, I saw several broods 

 of goslings swimming near the banks. At a pool in Montana, west of 

 Frenchman's River, a colony had established themselves to breed ; and 

 during the time when neither old nor young could fly, several dozen 

 were killed with clubs by some people attached to one of the surveys. 

 The frequent nesting of the species in trees, in various parts of the 

 I^forthwest, is perfectly well attested, though the fact did not com© 

 under my own observation. Birds apparently from the north were 

 common along the Mouse River in the latter part of September; a few 

 had made their appearance the last of August, and their numbers were 

 augmented during the month. 



BRANTA BERNICLA, (Linn.) Scop. 

 Bkantj Black Bkant. 

 Observed only during the migration. 



ANAS BOSCHAS, [Linn.) * 



Mallaed. 



Breeds abundantly throughout the region in suitable places. Flap- 

 pers about a week old were seen at Pembina June 20.
