no. 3640 HAWAIIAN BIRDS — CLAPP AND WOODWARD 29 



birds are complete enough for accurate aging, but the markings on 

 the wings indicate that both birds were less than two years old. 



Bryan and Greenway (1944) list this species from Laysan Island 

 on the basis of a fragmentary specimen in the Bernice P. Bishop 

 Museum. No observations or specimens of black-legged kittiwakes 

 have been reported previously from either Kure Atoll or Pearl and 

 Hermes Reef. 



Black-legged kittiwakes are circumpolar breeders that winter south 

 to Japan and northwestern Baja California in the Pacific (AOU, 1957). 



Gray-backed Tern Sterna lunata 



(Spectacled Tern) 



POBSP personnel have recorded many observations of gray-backed 

 terns on various islets of Pearl and Hermes Reef, from whence the 

 species has not been reported previously. These observations are 

 briefly summarized below:

 1963; 1000 adults, 40 nestlings, and many eggs seen June 18-22, 1963;

 1964; 500-600 adults seen Mar. 15-17, 1965; 40 adults and seven

 the Hawaiian Leeward Islands (Bryan and Greenway, 1944). 



Blue-gray Noddy Procelsterna cerulea 



Sibley and Amerson saw from eight to 10 blue-gray noddies on Gardner 

 Pinnacles June 16, 1963. In the Hawaiian Leeward Islands, blue-gray 

 noddies have been reported breeding on Nihoa, Necker, La Perouse 

 Pinnacle at French Frigate Shoals, and Kaula (Richardson, 1957; 

 Bryan and Greenway, 1944). None have been reported previously 

 from Gardner Pinnacles.
