Gene Kridler to Roger Clapp January 1970 p.4 
On page 7 under Necker - Christmas Island Shearwater - Birds seen, 
I have nothing in my notes but it’s possible that one of the other fellows 
may have seen a Christmas Island, I don’t recall at this time. Just kind 
of rummaging around at the back of my mind it seems to me that the bird 
was seen on the top of either Flagpole Hill or Summit Hill, but I’m not 
sure. I think I pointed it out to George Laycock (?) who was with us but 
I don’t have it in my notes. Now, we spread out over the island and every 
man was assigned several species and he devoted himself to only those species. 
The figure you should use would be 850. 
Yes, in the material which I sent to you we had listed Sooty Terns 
as 25% on eggs. Going back to my field notes I note that I had corrected 
the report to 75% and the 75% is correct, checking my reports I have Sooty 
Tern eggs very fresh and about 75% had laid, so use the figure 75* 
On your question 9 under Hawaiian Tern - you state that approximately 
80% on eggs. Does this mean that the rest were not nesting or that they 
were on young? This means that the rest were not nesting. Even though on 
previous March trips we did see at least 1 young, apparently they were a 
little later this year or we just didn’t see any young. Now, as you recall 
on the south slope of the island itself was quite sheer and there are 
Hawaiian Noddies down in there and it is possible that there might have been 
some nesti down there that contained young but we never have been able 
to get down there because of the sheerness of the cliff.

Shearwater the same would also apply to questions 8 and 9 'which would all 
concern Necker. 
Question 10 would also apply to Necker. I note in a report that you 
and John Sincock did a vegetation map. We did, we type mapped the island 
but the map isn’t fully prepared yet. John Sincock is working on it but he
