48 NORTH AMEEICAN SHOKEBIEDS. 



Spring migration. — ^Along the Atlantic coast the species is almost 

 unknown in spring north of its winter range ; the few known occur- 

 rences are in May. To the westward some dates of spring arrival are : 

 Galveston, Tex., March 24, 1891 (Singley) ; San Pedro River, Arizona, 

 April 17, 1902 (Howard); Monterey, Calif., April 6, 1903 (Bren- 

 inger) ; Redwood City, Calif., April 14, 1907 (Carriger and Pemberton) ; 

 Corvallis, Oreg., April 21, 1899 (Woodcock); southern British Colum- 

 bia, April 26, 1889, and April 20, 1905 (Brooks) ; Fort Kenai, Alaska, 

 May 12, 1869 (Bischoff); St. Michael, May 28, 1&74 (Turner). 



Most of the individuals have left southern Lower California by 

 May 10 (Balding) and the northern part by the middle of the month 

 (Kaeding). The species was still present at Owen Lake, Cahfomia, 

 June 1, 1891 (Fisher). Eggs have been found at the mouth of the 

 Yukon June 5 (specimens in United States National Museum) and 

 near Cape Prince of Wales, June 28, 1898 (Grinnell). 



Fall migration. — The first fall migrants were noted at Tulare Lake, 

 California, July 7-8, 1907 (Goldman), and the species was taken off 

 the coast of Venezuela July 7, 1895 (Robinson). The first of these 

 records probably represents birds in migration; the other, non- 

 breeders that had summered far south of the breeding grounds. 

 Some other fall records are: Southern British Columbia, average of 

 five years August 14 as the date of fall arrival (Brooks) ; Semiahmoo 

 Bay, Washington, July 15, 1857 (Kennerly); Santa Barbara, Calif.,

 1883 (Stone); San Mateo, Tehuan tepee, August 7, 1869 (specimen in 

 United States National Museum). The latest date in southern 

 British Columbia is September 11, 1889 (Brooks); Hayward, Calif.,

Sanderlmg. Calidris leucophxa (Pallas). 

 Breeding range. — ^The sanderling is a cosmopolite, breeding and 

 wintering in both hemispheres. It is known to breed north to 

 Point Barrow, -Alaska (Stone), Melville Island (Fisher), Grinnell Land 

 (Feilden), both coasts of Greenland (Bessels and Winge), the Taimyr 

 Peninsula, Siberia (Walter), and undoubtedly breeds on the New 

 Siberian Islands (Newcombe). It breeds south to Iceland (Gates), to 

 Cape Fullerton, Hudson Bay (Low), and to Frankhn Bay, Mackenzie 

 (MacFarlane) . 



Winter range. — Some sanderlings pass in winter to central Argen- 

 tina (Tambo Point, 44° S.: Dufnford), and to Talcahuano, central 

 Chile (Sharpe), 8,000 miles from the nearest breeding grounds;' while
