R.Clapp 1964 Oct. 3 Three days out of Oahu - Gilbert - Marshalls Few birds (149) seen. Very probable Pale-footed Shearwaters seen and a somewhat shaky Slender- billed Shearwater. Movie : Maniac - gaaah. Wedgetail numbers continued to decrease with 44 birds seen today with 30 ( %)of these seen in one flock. In this flock Wedgetails associated with Sooty Tern, "Bonin" Petrel, Pale-footed Shearwater, Commor Noddy, and White-necked Petrel. At 1659 a bird flew across the bow of the ship which may have been a Slender-billed Shearwater. Its flight reminded me of the Sooty Shearwater but the underwings were seen well and were much too dark for the bird to have been that species. The bird was all dark, with a dark bill, and appeared smaller than a Sooty Shearwater. Binion Amerson, who also observed the bird, was adamant that it was not a Christmas Island Shearwater or a Wedgetail. However, the foot color was not observed. The sun was not shining at the time. The only birds it could have been are these two species . A single Newell's Shearwater was seen flying SSE by Amerman and Wislocki. 12 Sooty Shearwater were seen today, none of which were in flocks. Oct. 4 Four days out of Oahu - Gilbert - Marshalls Fantastic increase in bird numbers caused by large flocks of Sooty Shearwater. 975 of this species were seen. Two more pale-footed Shear- waters were seen and 2 very probable Peale's Petrels. Wedgetail numbers showed a slight increase to 62 individuals. 25 ( %) were found in a flock mixed with Sooty Tern, White-necked Petrel, and a single Fairy Tern.
