119. 24 Feb. (cnot) HF outside 9.5" Width (stretched 13"); T 2.5"; Girth 23"; eyes open, iris brown; small nails - hind flipper, 3/4" nails on FF; curly black vibrissae; umbilicus 17" long, major portion only 4"; bleating, attempted to bite when we tried to stretch him out for weighing;, no teeth. Very good at crawling. Vulva of ? (232) was bleeding when first seen by Van Bolt at about 1500. We didn't weigh him untill 1800, after chow. The afterbirth was dry on the outside, but still moist within. While setting rat traps from 1830 until dark, we found two more antenna casualties - both Fairy Terns, one dead. The birds were not there this AM. There has been a great increase in the number of RTBs today - we [illegible] 60 in the air at one time, and many are on the ground. After dark we hear many, perhaps 6 or even more, Sooty Terns calling. They will begin descending upon the island soon. More Laysan banding and returns after dark. 25 Feb. Rat trapping in the AM. While Alan and I did rats, Bob went out and did some more Laysans. We got 100 rats, but only 4 new ones - i.e. C numbered rats. There were 2 double captures [illegible] Found one Bonin and 1 Frigate antenna kill today, the Frigate was an adult male in breeding condition, banded here in late 1963 (737-45411). The [illegible] came today and I learned that I should leave today. There is to much unfinished business to attend to, so I will stay until Sunday. Three Fairy Terns flew about us in the NAF today - calling and hovering overhead - the first time they have done this. There was a new (the 3rd) RTTB nest found by Bob. After setting rat traps, we band more Laysans and get many more recoveries. We are counting per centage marked vs. unmarked Laysans in the Central Roost, and the last two population estimates for that area, based on total number marked, has come out 2230 +- 10 the last two days. We are closing in on the total population in that area. To date we have 153 birds handled there.
