Pelidna alpina sakhalina (Vieill.). 
RED-BACKED SANDPIPER; AMERICAN DUNLIN. 
Uncommon transient visitor. 
Bigelow records ‘‘a few at Port Manvers in early September.” 
Weiz (’66) includes it as breeding at Okkak, but this is probably an 
error. 
Ereunetes pusillus (Linn.). 
SEMIPALMATED SANDPIPER. 
Common summer resident locally; abundant transient visitor. 
Audubon found this species nesting in early June in southern 
Labrador. He also adds this note (’42, vol. 5, 277): “About the 
period when these birds prepare to return southward, they congregate 
in large flocks, the young separate from the old. In Labrador this 
takes place from the beginning to the middle of August.” Bigelow 
found them breeding locally and describes the downy young. ‘Turner 
notes their breeding at the mouth of the Koksoak River. 
We saw only a few migrants on July 27th at Great Caribou Island. 
Calidris arenaria (Linn.). 
SANDERLING. 
Common transient visitor. 
The Sanderling has been noted by several observers during the 
migrations in various parts of the peninsula. Audubon says: ‘Some 
young birds were seen at Bras d’ Or, in little parties of four or five 
individuals....early in August, and they were already on their 
way southward’; and Packard says: ‘Three seen (2 taken) at 
mouth of Koksoak River.”’ Macoun reports that a pair was seen by 
Spreadborough on a small island in James Bay? June 16, 1896, and 
adds, “‘doubtless breeding.” As shore birds occasionally linger on 
the New England coast on their way north as late as this, and as non- 
breeding birds sometimes spend the summer considerably south of 
their breeding range this note should be received with caution.
