Punta Espinosa, Fernandina Island, Galapagos.
Alan Coy to take some lava samples and took him out to show
him where the plate areas of through lava were. In one of his
pools saw fish 18" inches long, longer than I recall seeing
in the pools before. Very hot, clear but windy, in the A.M.
Packed in the late A.M + early P.H., then helped Coy with his
sampling for a little. Spent the late afternoon taking
a few more pictures, trying to find a penguin on the land.
No luck in the latter. A large group of Blue-footed Boobies
was diving 1/2 of the pt. over a school of 30+ porpoises.
After the porpoise left the boobies all settled on the coast,
departing more or less singly to 3 & 4's for the rest of
of the afternoon - 2 + hours. The flock circled about so
that birds dove into the wind, circled away from the wind.
A couple of frigate birds in the fleet added much to the
confusion. Puffins and Noddies + a few Oceanites working
slowly and disinterestedly around the distant edge of the group
but not seriously in the center. Boobies dive from c. 75'
up, stay under 1-2 sec. Closer to live, sing a Boobie
were seen diving from much lower heights, often only 10-15'
and come up almost immediately. Shortly after this, saw a
group of 25-30 Noddies working, also in a rough circular
pattern just of the surface. When feeling the quality of
the jumpy quality of a Bonaparte's Gull, but the wing beat is much
gently
more shallow. They feed by dipping to the surface of the water
and picking off surface animals much like hi philadelphia.
When they decide to fly from one place to another their,
flight is more Stinger-like with the "swept-back" quality,
