 runs forward on either side to the throat and chin ; an ill-defined 

 black collar follows the white one at the top of the mantle. Wings 

 and wing-coverts brown, the shafts of the primaries white, an 

 increasing amount of white on the inner primaries and secondaries, 

 some of the latter being entirely white ; central tail-feathers like the 

 back with darker tips ; lateral feathers with dark subterminal spots, 

 and white tips ; the outermost pair entirely white ; below white

Pig. 117. — Head of ^gialitis hiaticola. x -\. 



Length 7-3; wing 4-9; tail 20 ; culmen 05 ; tarsus 0-95. 



The sexes are alike ; young birds are lighter than the adults and 

 have paler margins to the feathers of the upper surface ; there is no 

 black on the crown and the band on the foreneck is brown tinged 

 with buff in the middle. In the winter dress, as generally seen in- 

 South Africa, the black on the head and breast is partially replaced 

 by brown, and the band across the chest is more or less broken in 

 the middle. 



Distribution. — The Einged Plover breeds in the northern hemi- 

 sphere, from Cumberland Bay on the American side of Davis Straits 

 through Greenland, Iceland, and Northern Europe and Asia as far 

 as Lake Baikal. It is generally distributed in the British Isles both 

 as a migrant and a resident. During the northern winter it is found 

 throughout Africa from Cape Town to Cairo, but chiefly along the 

 coast lines.
