107. 4 Feb. Activity study all day, radar tower. Check the Laysans. There is very little action in the roost. 5 Feb. We worked on some Black-feet in the afternoon, doing six birds - blood samples, parasites, McBee info. It still takes about 15 minutes per bird. Band Bonin's this evening, band 16 new to the area, 10 returns, and 1 egg found on the ground. 6 Feb. Shore-bird and seal census. The find of the day was a White-tailed Tropicbird cruising over SE beach. I also found, after weasel told me, a Glaucus Gull, dead and rotted partially, onthe the beach. I plucked it and it will make a skeleton. FN 20429. The Fairy Tern we had, that got away yesterday, I found dead inthe Scaevola, in usable condition. We also found a Golden Plover banded only a week or so ago. 7 more Laysans were found dead - all rats, and two were in bad shape - one had to be destroyed. In two cases both an adult bird and its chick had been eaten. The siege of the rats continues. Spun down blood from yesterdays Black-feet (K63-68). About 50-60 per cent of the Laysan Nests have chicks. 7 Feb. In the morning we went about in the area surround- ing the central roost and got returns on the Laysans - we did about 150 birds. Birds onthe nest are being paint- ed with green stripe across the breast, those with walkers are being painted with a small green spot on the breast. Similar marks are being done in the SAF, although the paint used there is orange. Dennis and Bob went out and did more Laysans - in the SAF, after dark. I banded some Bonins, but they were extremely scarce - I found only 17 birds in all of SA2, SAF, and behind the fuel tanks. Only 9 needed bands. Time was 1000-1100. Did Blue-faced Booby behavior and got some interesting interactions with R19-20-23-and O3. There is a definite aversion of the head in all interactions between pairs, while antagonistic interactions make more use of the bill directed at the opponent. Ex. A Hd-tu w. by a male around his mate, almost without exception, features a bowing of the head down on the side of the breast away from the mate. T-wigs are on the side away from the female, and then placed in
