complete. Richardson ( 1957 ) visited the island in late March 1954, and 
his photograph shows half grown nestlings. He estimated the island population 
t 
at 1000 birds (pers. comm.). Aerial counts were made by personnel of the 
Bureau of Sport Fisheries and Wildlife between December 195 6 and June 1957 
and the population was estimated at 6,500 (Kenyon, Rice, Robbins, and 
Aldrich, 1958). Rice and Kenyon (1962) counted 3,665 birds and allowed for 
• f 
25 percent unemployed birds to arrive at an estimate of 2,700 pairs for the 
breeding seasons of 1958-57 and. 1957 - 58. In March 1961 the species was 
found nesting on the beaches and in small open sandy areas (Woodside and 
Kramer, 196l). The nestlings were one-third grown at this time. 
Population : Adults have been found on P0BSF visits in March of 1963 , 1964 
and 1965 , but not in August or September 1964 or July 1965 . Several thousand 
were present in March 1963 , and 3,500 in March 1965 , but an estimated 10000 
were present in March 1964. In March 1964 there were an estimated 1750 
nestlings on the island, and in March 1965, 1300 were found. By July 1965 
only 200 nestlingB remained.

Reproduction: The species nests in small numbers along the beaches and in 
If ' * 
clearings in the peripheral vegetation of the island. Egg-laying begins in 
« \ 
mid-November and most hatching occurs in January and early 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. 
Barge nestlings were found on Lisianski in late June I 89 I (Munro, op . 
cit .). Munter ( op . cit .) found well grown young, but still in pin feathers, 
fairly numerous on Lisianski in March 1915* Very few eggs were found. 
Nestlings, ranging from just beginning the contour plumage to nearly-fledged, 
V ’ ‘ / 
were found there in May 1923 (Wetmore, unpub. notes, 1923)* A photograph by
