The next line - observations from 2 recent March visits should read observations 
from 3 recent March visits and in parenthesis add (1969). Continuing down to line 6 
under paragraph of annual cycle - beginning with the word breeding season had begun. 
Change that to breeding season had begun which conflicts with the March records. 
Next sentence - next line began by at least mid May but suggested; I’m changing that 
to began by at least mid May and suggest an egg peak in July and not June, basing this 
again on what happens on Nihoa too about this time. You have made the statement that 
the September 1964 observations, and those from September 1966 indicate egg laying 
occurred in August or September and suggesting a fledging peak of late September to 
early October. Now I’m beginning to wonder about the breeding report in September 1953 
by Richardson. The March 1965* 67, 69 visits reveal few birds and none of which were 
known to be breeding. This confirms pretty much what we found to be the situation on 
Nihoa so I don’t know what Richardson bases his statement on there in 1953 when he said 
that 20 December 100-150 a definite breeding season beginning. Unless 1953 was very 
unusual from the other trips, but here again as I mentioned before, March 1965* 67, 
and I969 we found no evidence of breeding and very few birds, so this seems to be 
contrary to what Richardson claims he found there in 1953. So, you’re saying then 
thus 
that/the data available show that breeding has occurred in all months, but also suggests 
that the amount of breeding in some pairs is probably January through March, is 
I’m beginning to wonder about that Dec. ’53 data 
considerably reduced. Well, I don’t know,/ As I said that certainly is a variance 
from what I found out in these recent March trips unless there has been a change, 
which I doubt, so I’m going to suggest lining out thus the data available shows that 
breeding has occurred in all months but also suggests that the amount of breeding in 
some periods is probably January through March has been considerably reduced to saying 
that the amount of breeding in some periods is probably January through March is 
considerably reduced. Then in the table - on observations - Brown Noddy on Necker 
Island, and I have included the 1969 information.
