18 NORTH AMERICAN SHOREBIRDS. 



Records of migration in the interior of North America are not 

 numerous. In southwestern Saskatchewan the fall migration opened 

 July 13, 1906, with the arrival of a large flock, and a few days later 

 the birds were abundant. This is only four weeks later than the 

 departure of the northbound migrants, which had been seen in the 

 vicinity in 1905 from May 29 to June 15, and the following year as 

 late as June 14 (Bent). A remarkable flight of northern phalaropes 

 occurred near Terry, Mont., in 1899; during the last ten days of May 

 the birds were exceedingly abundant (Cameron). 



Wilson Phalarope. Steganopus tricolor Vieill. 



Breeding range. — The northern Mississippi Valley and the adjacent 

 parts of Canada form the principal summer home of the Wilson 

 phalarope. It breeds regularly as far east as northwestern Indiana 

 (Lake County; Butler) and the islands near Green Bay shore 

 (Schoenebeck) . Macoun records that a pair nested at Dunnville, 

 Ontario, near the northeastern shore of Lake Erie. Thence the 

 breeding range extends west through central Iowa (Newton; Preston) 

 and northern Colorado (Fort Collins; Cooke) to central California 

 (Lake Tahoe; Bliss; and Las Banos; Mailliard). Instead of pene- 

 trating the Arctic regions, as do other phalaropes, this species finds 

 the northern limit of its range in northern Manitoba (Lake Winnipeg; 

 Thompson), central Saskatchewan (Osier; Colt), central Alberta 

 (Edmonton; Macoun), northern Washington (Cheney; Johnson), 

 and probably southern British Columbia. 



Winter range. — The few winter records for this species come from 

 South America — from central Chile (Philippi) and central Argentina 

 (Durnford) south to Patagonia (Durnford) and the Falkland 

 Island (Sclater). There is a single record in fall migration for western 

 Brazil (Pelzeln). and one in May for central Peru (Berlepsch and 

 Stolzmann). Three specimens were collected January 19, 1890, at 

 Corpus Christi, Tex. (Sennett), but these were apparently laggards, 

 for the species is not usually seen in Texas after September. 



Migration range. — During the fall migration individuals wander 

 eastward to the Atlantic coast and have been noted from New Jersey 

 to Montreal. There is also one May record for Massachusetts (Baird, 

 Brewer, and Ridgway) and one June record for Maine (Smith). The 

 species seems to be unknown on the Atlantic coast between New 

 Jersey and Argentina. The principal summer home is in western 

 North America, and most of the species migrate south through 

 Mexico and along both Mexican coasts, and then apparently cross 

 directly to the west central coast of South America, since the species 

 is unknown in Central America east of Guatemala and in South 

 America north of Peru. 



Spring migration. — The Wilson phalarope arrives in central Kansas 

 on the average April 27, earliest April 23, 1885 (Kellogg); northern
