The Snow Goose, more commonly known as the "White Brant/' 

 is an abundant migrant in Ilhnois. comin"' south in October and 

 returning in January to March, according to tlie character of 

 the season. According to Mr. Nelson it visits us in large flocks, 

 either composed entirely of its own species or mixed with indi- 

 viduals of the larger race ( Chen hi/perhoren viralU) and the Blue 

 Goose, and in the central portion of the State frequents corn- 

 fields. 



The summer home of the Snow Goose includes the vast extent 

 of territory stretching from the "barren-grounds" of middle 

 Arctic America to Bering's Strait, and also a considerable por- 

 tion of northern Asia, which it traA'^erses until the eastern portion 

 of European Russia is reached.
