9 Fdb, Spent a good bit of time with the Laysans this 
Am. and after dark. The NAF and SAF were done, as well 
as SW beach and cdtral roost. Albatross checked, the 
foster chick at nest 29 is doing well. Another 1 
abandoned chick was found and given to nest 3&» the 
$ on the nest accepted it without any unusual behavior. 
The egg from 38 was removed and found to be rotten. 
It was a good night for Bonins, so while the three 
of us checked Laysans in NAF and SAF we banded Bonins - 
I also banded them in SA2 - we found 25 unbanded birds. 
We may be finally getting on top of the Bonins ther - 
of 16 birds found there only 5 needed bands. This is 
after several months of heavy and continual banding 
in the area. 
Checked NAF Blue-faced Boobies after dark to compare 
at-night count with the next day - found 2 new nests, 
both attended by the female, fl hoo,*- /Ko^»-f

10 Feb. Did the all day Rluo-faced Booby colony count. 
There were two new $? marked while on eggs - 
010 - (? 737-45121) and 
012 - 5? 667-35067) 
010 left the nest when marked at 1300 and did not 
return until I83O. 012 returned immediately to the 
egg, which had been numbered wi th magic marker. The 
bird placed the bill down as though to move the egg 
back under itself, then immediately straightened out 
and shook its head, as though in response to the ad- 
verse smell of the marking ink. This was repeated at 
regular intervals af about 20—30 secs, for the few 
minutes that we remained with her. We left so tnat she 
would not abandon the egg as 010 had done. I put up a 
'airy Tern (FN 20424) that is a little shabby around the 
eck. Skinning is becoming easier - I just need more 
ractio e. 
The three of us got some more returns on Laysans on 
the SE of runway area - 
It appears that there is some tendency for Blae- 
faced boobies to incubate at night, and for females to 
remain of the nest during the day - not an absolute 
thing, however. At 2200 last night 05 3-nd 07 > as well 
as B15, were on their respective eggs. By 0900 today 
06 and Bl6 were on their eggs, and at 1000 03 as well - 
all three females. By I83O that night all the males were 
back on the eggs. This must be further checked.
