a careful check of the entire interior in March 1965 one nestling was found 
and an estimated 25-00 adults and 1100 eggs were noted. The discrepancy 
between these data and that for March 1965 and 196k is probably due to 
incomplete censusing of the heavily vegetated areas on the two previous 
t 
Visits, An estimated 300 adults and 100 immatures were found at tho 
perimeters of the Sooty Tern colonies in July 1965. 
Reproduction : Munter (oj>. cit.) found one bird on an egg in March 1915* 
Eggs and nestlings were found by Wetmore (unpub. notes, 1923) in May 1923>

and a few eggs were found by Woodside and Kramer (op. cit .) in March 1961. 
Eggs were not found by the F0BSP in March of 1963 and 1964, but the 
party did not have sufficient time ashore to survey the entire interior. 
In March I965 the species was nesting throughout much of the bunchgrass 
area of the interior. Some birds were also nesting under Scaevola along 
the east beach. Only one small nestling was found, but over 1000 eggs 
were found in the process of banding the nesting colony. Only a few 
immatures and adults were found in August 1964, and the species was not 
noted the following month. Adults and immatures were found at the periphery

of the Sooty Tern, colonies dil July 1965. ' 
A Very small nesting colony utilizes Kure Atoll, 300 miles to the north¬

been found In July, and immatures in July and August. There Is some

season is a week or two later on each more distal island in the chain. 
Thus the cycle oh Lisianski would be expected to be a few weeks earlier 4-Vvour*
