Gould, P. J. 1963 (Wedge-tailed Shearwater) 7 After about an hour the flock had become widely dispersed and by this time the birds were soaring (no wing flapping) over much larger areas than when actively feeding. We have noticed that these Shearwaters while hunting often rise 10-15 or 20 feet above the water surface while banking for a turn. While these birds were feeding they did not do this, but usually remained fairly close to the water. After the fish school had quit jumping and the flock was spreading out, some shearwaters could be seen going up as high as 30 or 40 feet while banking. This is probably so they can get a good look around to see where the fish school had gone by seeing where other birds were displaying actual feeding behavior as opposed to hunting behavior. Earlier in the day we had observed a Wedge-tail to glide up over 100' in the air then after a few seconds set its wing and glide down to the water surface. September 12--Pacific Ocean, Grid Area 1000. Flock of ca. 50+ Wedge-tails, 2 Dark-rumped Petrel, and 10+ Sooty Terns. Flock milling, not feeding. Many birds sit on water.

It was shortly joined by second, third, fourth fifth through tenth birds in rapid succession. Once saw a lone bird sitting in the water that was not joined by other birds. It still sat for several minutes befoe flying over to join flock sitting in water. Out of 50+ Shearwaters only one was dark-phased.
