Amerman, Kenneth 1963 December 5--Continued work on albatross recoveries, covering the west side of the runway below the barracks and the entire east side. With few exceptions unpainted birds in the southern and eastern portions of the island are now unbanded ones. This makes the record keeping somewhat easier. Totals for the day: nine black-feet, four of which were incubating, and 153 Laysans, 110 on eggs. Roger Clapp arrived on the afternoon flight. We toured the beach from the dock to the north end of the runway before supper. December 6--Roger and I worked all day on vegetation plots, mapping Nos 1, 2, 4, and 1/5 of No. 3. Measurements are very subjective and variable, probably non-repeatable. Much difficulty in deciding what to measure (which plants and which parts of plants), especially in areas with much young grass. At Roger's suggestion we went through the north antenna field recording all Masked Booby bands. This is a good idea for several reasons-- any new individuals in the population can be recorded; it gives an accurate picture of numbers present and of sex composition; the birds are marked for further study. Males were painted with a stripe across the head, females with a spot, and unknowns with a central stripe. This procedure should probably be repeated every three months. The results of the evening's work are as follows: two new bands (737-47001, A-U, and 47002, A-F); 101 recoveries (13 juvenile, 40 ♂, 37 ♀, 11 U). Roger remarked about the birds' reluctance to vocalize, at least in the hand, which led to the high number of unidentifiable birds.
