no. 3640 HAWAIIAN BIRDS — CLAPP AND WOODWARD 9 



months of April, May, and June; downy chicks were present in June 

 and July; and nearly fledged birds were present in September and 

 October. The breeding cycle as indicated by our data is quite similar 

 to that reported for other islands in the Leeward chain. 



Pearl and Hermes Reef, Southeast Island: Far fewer Christmas 

 shearwaters occur on Pearl and Hermes Reef than on Kure Atoll. 

 The largest number of adults present was about 20 birds Sept. 25-27, 

 1966, with smaller numbers having been recorded in the months of 

 March, June, and August. Nests have been found on two occasions 

 (a nest containing an egg June 18-22, 1963, and three nests with young 

 Sept. 25-27, 1966). 



This species previously has been reported breeding on Nihoa, French 

 Frigate Shoals, Laysan, Lisianski, Midway, and Kure in the Hawaiian 

 Leeward Chain (Richardson, 1957; Robbins, 1966). 



Little Shearwater Puffinus assimilis (assimilis?) 



On Feb. 18, 1963, Amerson collected a male little shearwater (USNM 

 492974) in a colony of Bonin petrels (Pterodroma hypoleuca) near the 

 Chief Petty Officers' Club on Sand Island, Midway Atoll. The testes 

 of the specimen were 4 mm long, indicating that the bird was not 

 breeding. This specimen constitutes not only the first record for 

 any of the Hawaiian Islands, but it is also the first record for the 

 North Pacific Ocean. 



Dr. Alexander Wetmore, who compared the specimen with material 

 at the American Museum of Natural History, informed us that in 

 most regards the present specimen matches those of the race P. a. 

 assimilis but that it has more white on the under-tail coverts than is 

 typical of P. a. assimilis. Puffinus assimilis breeds on the Norfolk and 

 Lord Howe Islands in the southwestern Pacific (Murphy, 1927). 



Leach's Storm Petrel Oceanodroma leucorhoa leucorhoa 



(Leach's Petrel) 



On May 10, 1964, Wislocki found a Leach's storm petrel (USNM 

 494243) washed up on the beach of Green Island, Kure Atoll. The 

 specimen was identified subsequently as 0. I. leucorhoa by Gould. A 

 second Leach's storm petrel that washed up on the beach was col- 

 lected at the same locality Dec. 21, 1964, and was preserved subse- 

 quently as an alcoholic (USNM 503371). No Leach's storm petrels 

 have been reported hitherto from Kure Atoll or any of the other 

 Hawaiian Leeward Islands. 



Bryan (1965) reported another specimen that washed up on the 

 beach on Oahu and that was collected Oct. 26, 1964. Still another 

 specimen that washed up on the beach at Oahu was collected Jan. 5, 

 1967 (Throp, 1967).
