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 Oslifornia 
(Lake Tahoe; Bliss; and Las Banos; Mailliard). Instead of pene- 
trating the Aretic regions, as do other phalaropes, this species finds 
the northern limit of its range in northern Manitoba (Lake Winnipeg; 
Thompson), central Saskatchewan (Osler; 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 laggatds, 
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 South Caro- 
lina 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 South 
Carolina 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
