starting it. We had to anchor and they worked for 15 minutes to
repair it. We got back about 12:30. Ticks were also picked up
on Trig as were also many insects.
During the afternoon at Whale-Skate I took some color photos
of Frigatebirds and also some polaroid shots. Fred set up a mist
net for Noddies and a few were caught but due to the winds, it
didn't work so good. Fred and I both took a nap during the afternoon.
At dusk clouds again appeared to the N. E. and light rain fell
before dark. It soon cleared off though for a nice night. I
began banding Common Noddies and finished a string of bands
started earlier. I then began a short unfinished string on the
Grey-backed Terns. This proved to be quite a job as they flew
when approached and with our nets broken it took about 2 1/2 hours
and a lot of walking to do about thirty bands. During one of
my rounds of the beaches I came across one of the female turtles
digging a hole to lay eggs. She was about half through when I
began my watch (10 p.m.). The hole was about 1 foot square and
widened at the bottom. It was dug with the hind flippers (one at
a time) with the foot going down without touching the sides.
The underside of the flipper was brought toward the center of the
hole and the tip curved. This portion scooped up a small amount of
sand and then dumped it to the rear of the hole. The final
depth appeared to be about 1 1/2 feet deep or just as deep as the
flipper would go. The egg laying then began and I began counting.
