Gene Kridler to Roger Clapp 
Tape #1

but not very likely, because we got excellent counts. And a sample of 101 nests 
reveal 6% with no eggs, 5% with 1 egg, 58% with 2 eggs, and 15% with 1 young and 60% 
with 1 young and 1 egg which should give us a pretty good idea as the nesting phenology 
of this particular trip. Actually, I inserted the data on the bottom of the first 
page of tables and it should be over on the second where it belongs, so this then 
pretty much takes in the species accounts, Roger. You might wish to rewrite it on 
the basis of this latter data and my comments, it certainly should be but as mentioned 
before, the fact that Wetmore and Richardson are more or less well-known names in 
ornithology shouldn’t be any reason that their figures should be accepted any more 
than anybody else’s especially if they didn’t make any actual headcounts. I do have 
some questions on the reliability of some of the data especially that from the aerial 
estimates as compared to good ground coverage. Unless aerial photographs can be counted 
under a mike, under a sampling system, or completely, in many cases they are less 
reliable than a good ground count. Unless you’re counting ducks over a pond and 
can’t see them from the ground. 
I’m going to send you a-^copy of our March 1969 report which will also have data 
which will be of value to you in the island accounts for some of the other islands. 
Now, I’m going to check over your history page and see how that looks.
