Repro duct ion : The species nests primarily along the perimeter of the 
vegetated portions of the island and in some clearings. But large portions 
of the interior, even where the vegetation is sparse, have not Been utilized 
in the years in which POBSF visits have been made. Egg-laying begins in 
late-November and is completed by the end of December, and most chicks hatch 
' 
in February on Kure Atoll, 300 miles to the northwest. There is no reason 
to suspect that these dates should not also be valid for Lisianski. 
Large nestlings were found in late June I89I (Munro, 19^-2). Munter

About 30,000 pairs were estimated to have been present in the 1956-57 and 
1957-58 breeding seasons (Rice and Kenyon, 1962), but this figure was

Nestlings Were found by the F0BSF on a brief visit in early March 
1963, but no estimate of numbers was made. About 2600 were present in 
March 1964, but only 30 immatures remained the following August, and the 
species was absent in September 1964. There were 2750 nestlings present 
in March 1965, and 2000 were still present in July of that year. Many of
