18 Feb. (cont.) there were no RFB in the roost, and the rain came down. At 1850 I made the last roost count - there were 27 RFB (mostly by SE beach) and 14 Frigates in the roost, and 24 Frigates still soaring over SE beach where they had been all day. Frigates were chasing RTTB today, an one occasion an Ad. ♀ chased a RTTB so vigorously that it hit the water and bounced about 10-15' before stopping. The Frigate picked something up off the water and flew off. It was raining harder after dark, so we stayed in this evening. We got letters from both Bill and Chuck, both urging more granting agency type action - so, a big push will get underway fro more blood and ectoparasites. We are and have been operating at full capacity re. Berleze - 3'/day is all we have equipment fro. 19 Feb. Today we made a big push to band at least 100 Laysans - we got 114 or thereabouts, and got returns on another 60 birds. Boy am I tired; we will continue to work with Laysans until a reasonable percentage of the birds here have been handled. There are still a good 60-70 per cent unmarked bird on the island. Alan and I bled 25 Laysans, one of which was hung up on guy wires and lost a wing. We took ectoparasit es the new way (vials according to location) and dispatched the bird. He was too damaged - we never found the wing - to be of any further use. After chow I did Blue-faced Booby behavior, and Bob and Alan set the traps for our autopsy rats. Rain threatens. 20 Feb. Shorebird and seals census occupied a good portion of the day - we all managed to finish prior to the rainx which came and continued on into the night. We counted 466 Laysans with active nests, or a drop of 69 from the previous week. A total of 92 per cent of these had chicks (427 roughly), an increase from 80 per cent from last week. There was an increase from 1 Wandering Tattler to 10 this week. This was thex first week in the last three when the surf has been breaking over the reef, and the high numbersx of Tattlers is most likely due to the inaccessibility of the reef to them. We, in fun, pre- dicted before we did the count that a high number of Tattlers would be found. Alan did the beach, and his
