List of speciviens. 



GRUS AMERICANA, {Linn.) Temm. 



White or Whooping Crane. 



White Cranes were frequently observed in the Mouse River country 

 in August, September, and October, but always at a distance ; and I 

 was not so fortunate as to secure any specimens. There is no reason to 

 doubt their breeding in this section. To the best of my recollection^ 

 none were seen in the Missouri or Milk River region during the second 

 season. 



GRUS CANADENSIS, {Linn.) Temm. 



Brown or Sandhill Crane. 



. Conimonly observed after leaving Pembina, especially duiing the lat- 

 ter part of the season. In July, I noticed, in one of the topographi- 

 cal camps, the remains of a young bird, which had been caught alive. 

 It appears to breed over the whole region, in prairie country. In the 

 latter part of September and early in October, both this and the Whoop- 

 ing Crane appeared to be migrating southward, chiefly in the night- 

 time, when their hoarse, rattling croak often broke the stillness, or 

 sounded strong amidst the honking of the geese, the whistling of the 

 rushing wings of the wildfowl, and the slender pipe of the waders that 

 completed the throog of numberless migrants.
