Dear Bills 
Bob Sundell is expected to arrive hare with the Sire data 
this coming Monday, Then I should be able to fiviah the remain- 
in g work necessary on the forthcoming reports. 
While working on population dynamics^ of Boobies I notice d 
indications of breeding of both species in Oct. I don't have 
any record other than Ludwig^s field note#. !! 10-6-63 young 
of all sisea present " and "10-7-63 new eggs in Brown and Blue- 
faced nests". I hope you can locate some information of this an s 
send it to me, as well as any other info on last fall's breeders. 
It has also come to li^it that we need population estimates 
of a a ore exact nature. I ji{> know this will be difficult but 
necessary. The range of estimates should be cut as narrow as 
possible - even daily census counts of many species could be 
mu started. This could be done in most cases in conjunction 
with our other work and therefore not dislocate our prograa too 
much. It Is also Important that we run our activity studies from 
daifli to dunk. 
Guess thats all for now — 
As Always
