This is probably the most generally distributed species of the 

 family, since it is to be found along the banks of nearly every 

 stream, large or small, in the land. 



In Cook county, the Spotted Sandpiper is, according to Mr. 

 Nelson, a "very common summer resident." Mr. Nelson's note 

 concerning it continues as follows: "Arrives in April and departs 

 late in autumn. Breeds in abundance among the small sand 

 hills, along the Lake shore. Near Waukegan, the first of June, 

 1876, I saw Mr. T. H. Douglas secure over two dozen of their 

 eggs in considerably less than an hour. The nests were generally 

 placed under a small shrub or in a thin tuft of grass and the 

 eggs could be seen several yards away."
