no. 3640 HAWAIIAN BIRDS — CLAPP AND WOODWARD 23 



Western sandpipers breed along the coasts of western and northern 

 Alaska and winter from the coast of California, the coasts of the Gulf 

 of Mexico and North Carolina south on both coasts of Mexico to 

 northern South America (AOU, 1957). 



Pectoral Sandpiper Erolia melanotos 



In the last six years (1961-1966) at least 12 sight records of pectoral 

 sandpipers have been reported from the main Hawaiian Islands in 

 "Elepaio," and several sight records have been reported previously 

 from Midway Atoll (see Bailey, 1956, and Udvardy, 1961b, for a 

 summary of these records). None of these records have been verified 

 by the collection of specimens. 



Four specimens have been collected in the main Hawaiian Islands, 

 two from Hawaii (Henshaw, 1902), and two from Oahu (Bryan, 1905; 

 and a previously unreported POBSP specimen, USNM 493229, col- 

 lected Oct. 4, 1963, at Pearl Harbor, Oahu). No specimens have been 

 reported previously from the Leeward Chain. 



Specimens of pectoral sandpipers collected by POBSP personnel 

 from the Hawaiian Leeward Islands are listed by each island as 

 follows: 



Kure Atoll, Green Island: USNM 493227, Oct. 14, 1963; USNM 

 494322, 494323, 494324, Sept. 25, 1964; USNM 497221, 497222, 

 Sept. 21, 1966. 



Midway Atoll, Sand Island: USNM 493226, Sept. 17, 1963; 

 USNM 494325, Oct. 31, 1964; USNM 497218, 497219, 497220, 

 Sept. 29, 1966. 



Pectoral sandpipers breed from the Arctic coast of eastern Siberia 

 across northern North America to Southampton Island and winter 

 primarily in South America. They have been recorded casually from 

 Samoa, Australia, and New Zealand (AOU, 1957). 



Sharp-tailed Sandpiper Erolia acuminata 



Although there are many sight records of sharp-tailed sandpipers 

 from the main Hawaiian Islands (Udvardy, 1961b; see also miscel- 

 laneous field notes in the "Elepaio" for the years 1961-1967) and 

 although at least six specimens have been collected there (Munro, 

 1944; Rothschild, 1893), few records have been reported from the 

 Hawaiian Leeward Chain. 



The POBSP has many sight records of both this species and the 

 similar appearing pectoral sandpiper (Erolia melanotos) from the 

 Hawaiian Leeward Islands, but on several occasions a shorebird 

 identified in the field as a sharp-tailed sandpiper has proven to be a 

 pectoral sandpiper in the hand. We thus include here only the verified 

 POBSP specimen records as follows:
