P. DeBenedictis 1967 Feb 4 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,
