certainly scratch out that recent. You go on to say that these estimates indicate 
that the Sooty Tern is probably the most abundant breeder on Necker. Let's just 
take the probably out there, they are the most abundant breeder on Necker, with the 
possible exception of the Common Noddy, and when I checked back through our figures 
I still say that the Sooty Tern definitely is, Roger, and not probably, so let's 
scratch the probably out. 
The second page on Sooty Terns line 8 beginning with "over the island", you 
have birds nested on bare rocks on the Northwest Cape and main island. You apparently 
are referring to the March 1965 report however, since this is being coauthored, it 
isn't necessary to continually refer to a comment by somebody else in the report, 
especially in the case where I am one of the coauthors because I have first hand 
knowledge, and as such I am in a position to state what we have been finding within 
the last five years, so therefore: I have changed it to read: birds nest on bare 
rocks on Northwest Cape and the main island and under Chenepodium from above the 
cliffs to the tops of the ridges. This is fact, not based on one visit, but on a 
number of visits. Then the 1969 data is added for the table sheet, . 'r 
Brown Noddies - first sheet - first::paragraph - line 3 - I have changed mid to ^ 1 
late March. Also the next sentence beginning wit 
months but in most years.•. X have lined out some nesting may occur in all months and 
instead have started the sentence with In most years nesting apparently occurs principally 
'•'-between April or May and October-November. Next, population - in the second sentence 
for 
for 
I don’t think it’s necessary to say since a degree of error in visual estimates/large 
populations may be considerable,el,believe that just about everybody knows that. 
Therefore scratch that out and begin the sentence "we cannot conclude that there has 
been any change in the population since. n You begin with annual cycles, and say the 
various observations on the breeding status of these birds are insufficient to determine 
whether there is a usual annual pattern of breeding; not so; I believe we can safely say 
that there is a definite annual pattern of breeding with breeding as we mentioned before 
beginning probably in early April and going on clear through October-November.
