23 Nov. I tried catching all the Blue-faced Boobies that
had been marked with the Copper Kettle paint. This turn-
ed green, and blended in well with the green mark already
on the birds. All copper birds are being changed to
Black - still C series (cat black). Only 13 of the
birds were caught and remarked. All are numbered so
that the odd numbered bird is the male, the following
even number the ♀. Only exception is C17 (♀) and C18 (♂).
The birds were caught during the day, but are extremely
wary.
Since the day was so miserable - high winds and
much rain (.48"), a good part of the time was spent
doing paper work in the lab.
24 Nov. Before and after lunch we did x the plant plots,
8 of the 10 plots being evaluated. Data is gathered
in terms of number of plants of each species, and total
area covered per species, in each 25' sq. plot. The
weather was so bad that two plots off the lagoon side
in ravines between dunes could not be done because of
the blowing and stinging sand. Some Black-footed
Albatross had nested in these areas, and were waging a
losing battle. In one area 2 nests had been undercut
by the wind, and the eggs rolled out and down about 4'
of slope. Another black gooney was sitting facing the
sind, feathers ruffled and sand sticking in his eyes.
The bird looked as though it couldn't make it. An
abandoned egg lay 1' from the nest, the egg of another
bird. After dinner, I began staking out Laysan nests.
Four eggs were found in the NAF, and another nest was
imminent, both birds hovering over a newly formed nest.
All 5 spots were staked out - 25 nests will be so staked
as eggs are laid - a nest attendance study is planned.
Male birds are being painted with a green ring around
the neck; ♀♀s have green spots on the flanks directly
in front of the normal position of the wrists when the
wings are held into the body. A green spot is also
