United States south to the West Indies and northern South 

 America. 



In Missouri a common transient visitant in late April and May 

 and again in August and through September to October 17.

247. EREUNETES OCCIDENT ALIS Lawr. Western Sandpiper. 



Ereunetes pusillus. Ereunetes petrificatus (of western localities). 



Geog. Dist. Western North America, breeding chiefly in 

 Alaska and migrating through western United States r mostly 

 along Pacific coast, to Central and South America. Casually 

 eastward through the interior to the Atlantic coast in company 

 with the Semipalmated Sandpiper. 



Has been taken a few times in spring on sandbars in the Mis- 

 sissippi River by Mr. Chas. K. Worthen of Warsaw, 111. In 

 the spring plumage the Western is easily distinguished from 

 the Semipalmated Sandpiper by its bright chestnut on head, 

 back and rump. 



248. CALIDRIS ARENARIA (Linn.). Sanderling. 



Tringa arenaria. Calidris calidris. Calidris rubidus. Beach Bird. 



Geog. Dist. Almost cosmopolitan; breeding in arctic and 

 subarctic regions and in America, migrating through United 

 States, both coastwise and through interior; wintering from 

 California and southern Texas to Chile and Patagonia. 



In Missouri the Sanderlings were formerly fairly common 

 transient visitants from the latter part of August to October. 

 They were found in small flocks on the extensive sand bars in 

 the Mississippi River, frequenting the same place for weeks, 

 together with other sandpipers and plovers. In spring they 

 appeared to be more in a hurry, never remaining long in one 

 place. Like all waders their numbers have greatly decreased 

 during the last twenty years and the species seems never to have 

 been as common westward as in the eastern part of the state. 



249. LIMOSAFEDOA (Linn.). Marbled Godwit. 



Scolopax fedoa. Limosa foeda. Marlin. Dough Bird. 



Geog. Dist. North America to southern Canada; rare on 

 the Atlantic coast. Breeding formerly from Iowa, Wisconsin 

 and eastern North Dakota northward, now restricted mainly
