TRINGA. 



coasts it is a resident. It winters in some numbers on the coasts of the British Islands, 

 on the southern shores of the North Sea, and sparingly on the northern shores of the 

 Mediterranean. It probably breeds on both coasts of Behring Straits and across Arctic 

 America ; but more or less isolation with its attendant differentiation appears to have taken 

 place in the Behring Sea, so that the birds from this district are regarded as at least 

 subspecifically distinct. It has not been recorded from Japan, but I have a skin in my 

 collection in winter plumage (which has the basal half of the innermost web of the 

 innermost primaries white) obtained by Wosnessenski in the Kurile Islands. It winters 

 on the shores of the Great Lakes and on the coasts of New Brunswick, occasionally 

 occurring on the Bermudas and the Azores. A solitary individual is said to have wandered 

 as far as South Africa (Finsch, Abhandl. nat. Ver. Bremen, iii. p. 65), but the statement 

 requires confirmation. 



Like its near relation the Dunlin, the Purple Sandpiper breeds far south and winters 

 far north.

The differences between the Aleutian Purple Sandpiper and the typical form have 

 already been pointed out. The former appears to replace the latter iu the North Pacific, 

 but the two forms are very closely allied.
