( Kridler ) Population estimate of 8,000-10,000. These birds were distributed over 
most of the island with the greatest number on northwest Cape. Nests contained eggs

Estimated total island population- 25 
Breeding --(no notes -- indicating no breeding ?) 
Estimated 25 birds although only 3 were actually seen. This 
is in considerable contrast to last September when we thought that perhaps 10, 000 
were present. 
Sept.10-11, 1966 
(Kridler) 
Ro countes were made but they were extremely abundant. Estimated 
at least 8, 000-10,000 adults with another 000+ chicks. Few nests still contained 
eggs but we estimated that approximately ^^ 0 |o had already hatched. Young were in 
all stages but ™ainly from l/2 to 1/3 grown. A very few were capable of flight.. 
They were distributed all over the island with the Rorthwest Cape most favored. 
Another favorite area was Annexation Hill. We did notice that the noddies when 
they were brooding chicks would brood them either under the left or right wing and 
not under the body itself.

(Rept): Population estimate: Rone (Rotes) Rone were observed, 
Main part of island: 8,200, Rorthwest Cape: 850 , downy chicks on 
the main part-ef-the island : 6lj on the Rorthwest Cape: 25 ? 
nests with one egg on the main part of the^ island: 1,580, on the Rorthwest Cape: 600. 
These birds were scattered all over the island and the nest and egg counts are a 
minimum. There were many more we were unable to count because of the lack of time.
