were present, and their breast plumage was just coming in. The island was 
visited by Richardson (195?) in late March 1954>, and a photograph in his 
paper shows half-grown nestlings. He estimated the island population at 
3000 birds (pers. comm.). Personnel of the Bureau of Sport Fisheries and

Wildlife made aerial surveys of the island between December 1956 and June 
1957 and estimated that 68,000 birds were present (Kenyon, Rice, Robbins,

Rice and Kenyon ( 1962 ) estimated that J0 } 000 pairs were present in 
the 1956-57 an< i 1957*58 breeding seasons. However, they state that they 
could not accurately count Lisianski from the air due to the dense vegetation.

Their estimate for Lisianski was derived by comparing the aerial photographs 
with some from Eastern Island, Midway Atoll, where nesting density was known 
from ground counts. The POBSP has / surveyed both Eastern and Lisianski from 
the ground, and it has been our experience that very few pairs nest through¬ 
out the vegetation on the latter island, but do on-the former. Therefore, 
it seems likely that the Laysan Albatross population of Lisianski does not 
reach the magnitude indicated by Rice and Kenyon.

Woodside and Kramer (l96l) .visited the island in March 1961 and found 
most of the nests on the upper beach and in clearings, with only marginal 
nesting in the dense grass of the interior. They found the nestlings about 
one-third grown at this time. 
Population : Adults have been found on POBSP visits in March of 1963 , 64- and 
65, but not in August or September 1964- or July 1965 . Many thousand adults 
were present in March 1963,but the number of nestlings was not estimated.
