 hemisphere. In America breeding from Hudson Bay along 

 Arctic coast to Alaska and migrating through United States 

 both coastwise and in the interior, to the West Indies, Columbia 

 and Brazil. 



In Missouri a rather rare, formerly irregularly common, 

 transient visitant from the middle of April to the middle of May, 

 and in fall to the end of October. Latest record, November 

 5, 1889, when Mr. Chas. W. Tindall killed one at Independence.

Geog. Dist. — Western hemisphere except coast of Behring 

 Sea. Breeds in Arctic regions from Parry Islands to Norton 

 Sound. Migrates through United States, chiefly the interior, 

 in spring, and along the Atlantic coast in fall ; very rare in Cali- 

 fornia. In winter to South America as far south as Patagonia. 



In Missouri a common transient visitant from latter part of 

 March to nearly the end of April, and rarely in fall. Formerly in 

 very large flocks about the middle of April on the marshes and 

 fields of northern Missouri, where it still occurs, but in much 

 smaller numbers. The new law of 1905, which forbids spring 

 shooting of plovers in Missouri, will probably be instrumental 

 in increasing plovers of all kinds. Earliest date in spring, 

 March 23, 1872, St. Louis (Hurter collection) ; latest April 30, 

 1892, Keokuk (Currier). Fall records are from Keokuk (Currier) 

 October 19, 1902, October 29, 1893 and November 9, 1895; 

 from Independence, November 8, 1892, when Mr. Chas. W. 

 Tindall killed one on a sand bar in the Missouri River.
