BUFOUS-NECKED SANDPIPER 217 



DISTRIBUTION 



Breeding range. — Northeastern Siberia (probably the delta of 

 of the Lena River and the shores of the Sea of Okhotsk, certainly 

 at Providence Bay, Kooshka, and Cape Serdze) ; and northwestern 

 Alaska (Cape Prince of Wales, Wainwright, and probably Nome.) 



Winter range. — The Malay Archipelago, the Philippines, and 

 Australia. 



Migrations. — First arrivals reach Gichiga, Siberia, May 28, and 

 they are mostly gone by September 11. They pass Bering Island late 

 in May and again during the first half of September. One taken by 

 G. Dallas Hanna on St. Paul Island, August 27, 1920. They have 

 been taken in the Philippines as early as August 13. Japan, China, 

 and Lake Baikal are included in the migration route. 



PELIDNA ALPINA ALPINA (Linnaeus) 



DUNLIN 

 HABITS 



The well-known European dunlin has occurred occasionally as a 

 straggler on our eastern coasts, Massachusetts and New York. It 

 has probably occurred here more often than is known, for it closely 

 resembles our red-backed sandpiper, especially in winter plumage. 

 There is no reason why it should not occur here more often, for it 

 is now known to breed regularly on the east coast of Greenland. 



Thayer and Bangs (1914) thought, at one time, that we should 

 recognize three races of the dunlin, which they designated as follows: 



PeUdna alpina alpina (Linn.), western Europe. Small, with shortest, 

 straightest bill; upper parts darker with less reddish; heavily spotted (some- 

 times almost streaked) with dusky below, between throat and black breast 

 patch. 



Pelidna alpina pacifica Coues. North America. Much larger, wifh much 

 longer, more curved bill; upper parts paler with much more reddish: much 

 less heavily spotted with dusky below, between throat and black breast patch. 



Pelidna alpina sakhalina (Vieill.) East Siberia. Size and length and shape 

 of bill intermediate between that of the other two forms; colors much paler 

 than in either; upper parts very pale reddish, much mixed with gray; b 

 of neck and top of head nearly wholly pale gray; below very slightly spotted 

 with dusky, between throat and black breast patch (much less so, even than 

 in pacifica). 



Recently, Mr. Bangs tells me, he has come to the conclusion that 

 the Siberian bird should not be separated from the American, as the 

 characters are too slight and rather intermediate. This seems like 

 a wise decision, as the naming of intermediate-, is undesirable. 



Much has been published on the habits of the dunlin, but, as they 

 differ but little from those of our birds, it seems superfluous to write 

 its full life history.
