 the Hawaiian Islands, Koahualu, August G, 1900, and October 14, 

 1900; once at Hopedale, Labrador; and several times in Greenland, 

 in summer and fall. Observed in Labrador, Rigolet, June 24 to 

 July 8, 1882, and Davis Inlet, July 18, 1883. In Europe it has 

 apparently been detected only in the British Isles, where there are 

 several records from Scotland and Ireland and the southern counties 

 of England.

WHITE-RUMPED SANDPIPER 



HABITS 



The white-rumped, or Bonaparte, sandpiper is a great traveller; 

 it breeds in a limited area on the Arctic coast of North America and 

 winters in extreme southern South America. 



Spring. — From its winter home in South America, this sand- 

 piper makes an early start; Dr. Alexander Wetmore (1926) writes: 



At Guamini, Buenos Aires, from March .'* to 8, white-rumped sandpipers 

 were encountered in northward migration from a winter range in Patagonia. 

 The species was fairly common on March 3 and increased greatly in abundance 

 on the two days that followed. The northward journey was apparently as 

 concerted as the movement that carried the birds southward, as on March 6 

 there was a noticeable decrease in their numbers, and by March 8, though 

 the birds were still common, the bulk of individuals had passed. They ar- 

 rived in flocks from the southward, often of several hundred individuals, that 

 whirled in and circled back and forth along the lake shore to decoy to birds 

 feeding on the strand or to rise again and continue swiftly northward. Those 

 that paused kept up a busy search for food along the muddy beaches in or 

 near shallow water, or in company with little parties of buff-breasted sand- 

 pipers on the drier alkaline flats back of the shore line. In early morning 

 they were especially active and were in continual movement. Occasionally
