SEMIPALMATED: PLOVER. 89 
Sound. (Townsend). It. seems to be more common in the middle 
Yukon Valley (Bishop) than on the coast. . 
This plover breeds south to Sable Island (Dodd) ; southern New 
Brunswick. (Cheney); the: Magdalen Islands (Brewster); southern 
James Bay (Todd); York Factory, in southern Keewatin (Preble); 
probably rarely in northern Manitoba (Macoun); on the Slave River 
“of southern Mackenzie (Preble); Lake .Marsh, southern. Yukon 
(Bishop); to the mouth of the Yukon, Alaska (Dall and Bannister) ‘ 
and on the Queen Charlotte Islands, B. C. (Brooks). 
Winter range——The species winters on both. coasts of South 
America—south to Port Desire, 48° S.(Seebohm), on the east coast, 
and to central Chile (Schalow) on the west; thence through northern 
South America, Central America, and the West Indies to the southern 
Bahamas (Bonhote), Florida (Worthington), the coast. of Georgia 
(Helme), South Carolina (Kendall), Mississippi (Allison), and Loui- 
siana (Beyer); on the Pacific coast of Mexico, north to southern Lower 
California (Brewster).. In winteritis thus one of the most widely dis- 
tributed of the shorebirds. , 
Migration range.—The species is a. common migrant in eastern 
North America west: to the eastern ‘parts of Texas (Beckham), 
Nebraska (Wolcott), and Saskatchewan (Macoun). Thence over the 
plains and throughout the whole Rocky Mountain district it is almost 
unknown, but reappears on the Pacific Coast, and ranges west in 
migration to the central Aleutian Islands (McGregor), the Pribilof 
Islands (Prentiss), and even occasionally across Bering Strait to the 
coast of Siberia (Nelson). = . 2 Te 
Spring’ migration.—At' least' four-fifths of the dates on the spring 
migration of this species fallin May. Thisis true for the entire district 
between the winter and summer homes, and the dates indicate that 
the migration in the United States occurs chiefly between May 10 and 
June 1. An unusually early individual was taken April 7, 1875, at 
Erie, Pa. (Sennett). Other spring dates are: Magdalena Bay, Lower 
California, March 12, 1889 (Bryant); Monterey, Calif., April 17, 1903; 
Vancouver Island, British Columbia, April 28, 1894 (Kermode); 
Mount McKinley, Alaska, May 17, 1908 (Sheldon); Kowak River, 
Alaska, May 30, 1899 (Grinnell); Pea and Bodie islands, North Caro- 
lina, April 25, 1905 (Bishop); Lincoln, Nebr., April 27, 1900 (Wol- 
cott); southern Ontario, average of six years May 18, earliest May 8, 
1885 (Garnier); Melville Peninsula, May 31, 1882 (Parry); Wellington 
Channel, June 6, 1851 (Greely). The species was taken in Cuba as 
late as May 22, 1900 (Palmer and Riley); southern Florida, May 25, 
1886 (Scott); from New Jersey to the Great Lakes it remains regularly 
to the first week in June—latest Oberlin, Ohio, June 17, 1904 (Jones) ; 
latest Worth, Ill., June 20, 1894 (Woodruff); and along the coast of 
Maine nonbreeders occur all summer (Knight).
