Banded, collected, blood sampled --none 
About 1,000 chicks were present on the shoreline, as determined by actual count 
of 993 locals and 10 adults on 18 June. Since the species was almost entirely 
confined to jbhe relatively narrow beach, this count was considered to be nearly 
complete. These birds may have been slightly more advanced that Laysan 
Albatross chicks. A larger percentage -- about one thifed — had lost the down 
from their heads and necks, and fwer adults were attending young, 1 per 100 
chicks as compared with 1 per 20 to 25 young for Laysan Albatross. Also 
Black-foot chicks practiced flying more and many were capable of short 
hopping take off attempts.

Actual nest counts conducted on all but Laysan and Lisianski. The Lisianski 
population appeared quite small (ca. 500 nestlings.) (CDH notes) Population

Bests were found all around the island, with heaviest concentrations found along 
the west beach, south beach, and along the southern part of the east beach. 
An occasional bird was found throughout the interior. We counted 1, l6l chicks 
on our survey; this probably represents most of the population. I would estimate 
that pp to 1, 200 chicks were on the illand. Culmen measurements were made 
to determine more accurately the range of hatching data. Weakened birds were also 
found along the ocean beach. \ 
One area at the southeast corner of the island had a large concentration 
of nestlings. I measured the area and counted the immatures found in the 
area. There is no way to tell the mortality to .this data but I assumed there 
would be at least a 25 % and I corrected the density figures accordingly. 
The area was 110 yards by 68 yards, giveing a total of 7 ? 480 yards squared. 
' This would be one nest per 26.5 square yards. If you assumed a 25^ pertaility 
to this date, there would be 380 original nests giving a nesting density 
of one nest per. 19.6 square yards. These figures are not close to the maximum 
density figures for this species. 
June 2-6, f 67 (FCT) Total est. pop. 3,000 +. Chick count: ll6l. 
The chicks were the same size as on Pearl and Hermes and also restricted to 
the beaches. Again only a few adults were seen feeding the young.
