WILSON PLOVER. 93 



April 8, 1857 (Hepburn). The species has been taken at Cavanche, 

 Chile, in May (Schalow), and at Coquimbo, Chile, in June (Sharpe). 

 It may prove to be resident in Chile. 



Eggs have been taken in Los Angeles County, Calif., April 25, 

 1899 (Robertson), and young, May 1, 1897 (Grinnell); also eggs at 

 Santa Cruz, CaHf., April 16, 1873 (Cooper). In southern Kansas the 

 eggs are laid in late May (Goss) . 



Fall migration. — FaU migrants have been. recorded in September 

 from Guatemala (Salvin), and in October from the southern limit of 

 the range in Chile (Schalow). The species has been taken at San 

 Francisco as late as November 1, 1898 (Homimg). 



Hon.g'olian. Plover. Mgialitis mongola (Fall.). 



In the summer of 1849 Captain Moore of the Plover in his search 

 for Sir John Franklin touched at the Choris Peninsula, Alaska, and 

 while there secured two specimens of the Mongolian plover — the 

 first and only individuals ever taken in North America. The breed- 

 ing range of the species is on the opposite side of Bering Sea; on 

 the Commander Islands, and in northeastern Siberia. It migrates 

 through Japan and China, and winters from the Philippines to 

 Australia. 



[Azara Bizxg Plover. Mgialitis collaris (VieiU.). 



The Azara ring plover is the only true shofebird. found in Central America that 

 does not range north to the United States. It has a wide distribution in South 

 America, south to Argentina, extends north to southern Mexico, and has been taken 

 once on Grenada, West Indies .J 



Wilson Plover. OcJiihodromus milsonius (Ord). 



Breeding range. — ^The Wilson plover is found in summer through- 

 out the northern Bahamas (Bonhote) and along the Gulf coast of 

 the United States from Florida (Scott) to Texas (Merrill), and 

 breeds along the Atlantic coast at the present time as far north as the 

 islands off the southeastern coast of Virginia (Dutcher) ; many years 

 ago it bred ocpasionally on the New Jersey coast (Wilson). The 

 summer status of tlxe species on the Pacific coast of Lower California 

 is not yet definitely settled. It was found common at Abreojos 

 Point, June 17, 1897 (Kaeding), but whether or not it was breeding 

 was not determined; 



Winter range. — ^The winter range is not known with gertainty, 

 because the West Indies are occupied by a resident subspecies, 

 rujinuchus, and sufficient material has not yet been accumulated to 

 determine the relative areas occupied by the two forms in winter. 

 The northern form winters as far north as southern Florida-^form- 

 erly northern Florida (Scott) ; the coast of southern Texas (Merrill) ; 

 Guaymas, Sonora (Nelson) ; and La Paz, LoWer California (Belding). 

 Thence it ranges south to the Pacific coast of Guatemala (Salvin) . 



Spring migration. — Dates of arrival on the Atlantic coast are : 

 Amelia Island, Florida, April 2, 1906 (Worthington) ; Darien, Ga.,
