C. H. GILBERT CRUISE 74, August 1964 This cruise was designed to study the fish species present in ocean currents at this time of year. The fish were to be found by observing bird flocks, especially terns, which seem to follow fish schools more closely. Dayle Husted (S. I. personnel) boarded ship at Kaileua, Hawaii, August 14, 1964. The cruise covered the area around Hawaii, north of the Hawaiian chain to Kauai, the channel between Kauai and Niihau, and northwestward to south of Nihoa, then back to Honolulu on August 23. Dayle Husted was to observe the feeding behavior of the birds of the various flocks. FEEDING BEHAVIOR OF BIRDS IN FLOCKS Wedge-tailed Shearwater Wedgetails were observed feeding in two major ways -- either sitting on the water and dabbling or flying above the water and diving into the water. When sitting on the water they keep the wings folded, paddle around and put their head and neck under water to feed. When flying above the water, they dive to just above the water and put their head and neck under the water. During this action their wings are continuously beating. After sitting on the water they take off by lifting their heads out of the water and run along the surface until becoming airborne. The dives were not very deep-- probably less than a foot-- and lasted 3 or 4 seconds or less. Some Wedgetails were observed to alight on the water, keep their wings beating, or raised above their bodies, thrust the head and neck under water, and then take flight after a short run.
