Husted, Dayle N. 1964 34 The terns follow the fish school very closely, the shearwaters meander around more. The terns seem to stay at the head of the fish school. Position 20° 18' N 155° 09'. August 17--A very dark Dark-rumped Petrel came very close to the ship this morning. At 0610 an immature Sooty Tern circled the ship two times. No adult was present. The young bird chirped several times. We were in another flock at 0927. On way to flock I saw a very large Albatross, it was much larger than the Frigate it passed. Position of flock 21° 59' N 156° 51' W. Some of the Wedgetails were sitting just dabbling around. The Sooty Terns are up above and the Noddies are down below. In another flock at 1023. Two Masked Boobies were sitting in water ducking their heads. Many Noddies and Hawaiian Noddies are sitting on the water just dabbling around. There is also a good many Wedgetails sitting on water. Boobies were seen too just collapse in air and dive into water head first. No luck in bringing fish to the surface. 1510 we are heading toward another flock. This is a very large flock. The Boobies are gliding low over the water and then diving in, others are up higher then diving in. There are many Wedgetails and Noddy Terns sitting on the water. The Noddies seem to be able to come to a stop by moving their wings in a forward motion. The Sooty Terns stay up above the flocks, the Noddies are down below. One of the crewmen just told me that a flock of Boobies indicate Mahi Mahi school. Position of flock 22° 06' N 157° 32' W 1620, in another flock. Several Noddies were seen swimming along with their heads under water.
