110. 9 Feb. 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 catral roost. Albatross checked, the foster chick at nest 29 is doing well. Another abandoned chick was found and given to nest 38, 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. A House Mouse caught. 10 Feb. Did the all day Blue-faced Booby colony count. There were two new ♀♀ marked while on eggs - 010 - (♀ 737-45121) and 012 - ♂♂ 667-35067) O10 left the nest when marked at 1300 and did not return until 1830. O12 returned immediately to the egg, which had been numbered with 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 of about 20-30 secs. for the few minutes that we remained with her. We left so that she would not abandon the egg as O10 had done. I put up a Fairy Tern (FN 20424) that is a little shabby around the neck. Skinning is becoming easier - I just need more practice. The three of us got some more returns on Laysans on the SE of runway area - It appears that there is some tendency for ♂ Blue- faced boobies to incubate at night, and for females to remain off the nest during the day - not an absolute thing, however. At 2200 last night 05 and 07, as well as B15, were on their respective eggs. By 0900 today 06 and B16 were on their eggs, and at 1000 C8 as well - all three females. By 1830 that night all the males were back on the eggs. This must be further checked.
