Much less nesting area was available to this species than at Pearl and Hermes 
Reef. Again only large young, about 30 in number were seen. At least three 
were observed to swim out and float for long periods on the lagoon, wings 
outstretched , facing the wing.

Hestlings were one-fourth to one-thrid grown. Rests were primarily along the 
perimeter of the vegetation, and in some clearings in the interior, but large 
portions of the vegetated area, even clearings, are devoid of albatrosses. Adult 
night population was 6-10 thousand birds. (RBC summ) Present in relatively 
small numbers considering the size of the island. 2,200 chicks banded out of 
an approximate total of 2,500 to 3,000. Adult population estimate set at about 
10,000. (DBS summ) There seemed to be a larger pereent of the population that 
was weak from not being fed. The chicks in the Eragrostis were often weak. 
Possibly becasue of the —--. We most commonly found Laysan chicks in the open 
areas where there was no Eragrostis (only Ipomea indica )Clapp and I banded 700- 
800 birds on the beach.The Laysan that nest in tall Eragrostis may land 
at their nests but they appear to walk to the beach to take off again. Mult 
population probably 8-10 thousand. There are many more times this figure that 
use the island.

The status of Laysans was practically identical on both Laysan and Lisianski. 
Almost ^100 % of the birds present were young of the year. Ro adults were observed 
on Lisianski . A considerable number of carcasses was noted on Laysan but 
relatively few were found on Lisianski.
