The Sanderling is a common visitor to the coasts of all countries of the Old and 

 New Worlds during winter or on migration, but its breeding-haunts are in the Arctic 

 Regions, and very few authentic eggs have been taken. It was found nesting in 

 Grinnell Land by Colonel Feilden during the British Arctic Expedition under Sir 

 George Nares, and it is believed to have bred in Iceland ^^. A nest was obtained by 

 MacFarlane on the tundra east of Anderson River ^^, and the species will probably be 

 found to breed throughout the whole circumpolar region. 



During the autumn migration the Sanderling is found in some numbers on the 

 coasts of both hemispheres, passing southward to its winter-quarters. It seems also 

 to winter in certain localities in Central America. Grayson says that the species is a 

 wanderer at Mazatlan, being sometimes found in flocks on the beach in September, 

 October, and the winter months ^^. Salvin met with it on the Pacific coast of 

 Guatemala, where many individuals were frequently seen ^. 



Wherever C. arenaria is found on its autumn migrations, it is generally noticed 

 in flocks, keeping apart from the society of Dunlins and other Waders, and is 

 recognizable by the amount of white which the bird displays when on the wing. 

 Its habits otherwise resemble those of the small Sandpipers which frequent sea- 

 beaches. 



The nests, so far as hitherto discovered, consist of a depression in the open ground 

 or in a dwarf willow, lined with decayed leaves or catkins. TTie eggs are four in 

 number, " buflfish or brownish-olive, faintly spotted with olive-brown or bistre, with
