 Calumet Marshes." 



While the range of this species includes the whole of 

 America, it is much more common in eastern than in western 

 North America. It breeds in the cold temperate and subarctic 

 regions of the northern continent, and winters as far south as 

 the southern portion of South America.

A common migrant. I feel quite certain that a number may 

 nest within our limits for I have observed adults in Cook County 

 throughout the summer. I can find no records which show 

 that the eggs of this species have ever been taken within our 

 area. The Solitary Sandpipers arrive early in April, the ma- 

 jority soon passing farther north. In the fall, they leave our 

 vicinity in September. Mr. E. W. Nelson says:* "I have 

 several times taken young of this species just able to fly, and 

 have observed the adults throughout the breeding season. I do 

 not think there is the slightest doubt of its breeding in this 

 vicinity." 



The range of the Solitary Sandpiper covers the whole of 

 North and Central America and a large portion of South Amer- 

 ica; it at least migrates as far south as the Argentine Republic. 

 It breeds chiefly north of the United States.
