day. Three to six birds were present for the last three days. The in- crease of albatrosses came at the same time a notable drop of surface temperature was recorded. Of the 14 birds for which rump color was noted six (42%) were white-rumped. This is about the same as the overall per- centage of white-rumped birds in the present Grid survey (15 out of 42; 82%). Sooty Shearwater (Puffinus griseus) # Obs. = 2 Two Sooty/Slender-bill Shearwaters were seen on 14 July. One had "light" underwings, the other was not seen well, but both were probably this species. Both birds were traveling in a west-southwest direction. Pterodroma sp. # Obs. = 2 Both sightings were on 12 July. One may have been a P. externa. Shearwater/Petrel # Obs. = 3 Three shearwater/petrels were observed on 16 July in the area of the most rapid surface temperature drop. Two of the birds were tentatively identified as Kermadec Petrels, one light-and one dark-phase. Red-tailed Tropicbird (Phaethon rubricauda) # Obs. = 1 A short-tailed bird (subadult ?) on 17 July (ca. 30° N; 134° W) was closer to the North American coast than the Hawaiian Islands. White-tailed Tropicbird (Phaethon lepturus) # Obs. = 1 This was the only bird seen on 13 July. Tropicbird sp. # Obs. = 1 Seen on 14 July, this bird was noted as follows: "Sitting on water, large, pinkish hue, dark bill, long-light tail." Jaeger sp. # Obs. = 2 Two birds were seen together on 12 July. Section "C" Pt. Arguello 23 July One hour of observation was run from the helicopter rendezvous 11 miles off Pt. Arguello to A Point 20 miles southwest of Pt. Arguello. One- hundred-sixteen birds of six species were observed. This area is well out- side of "pelagic" areas (see Figure #2). Albatrosses were present but low in numbers; no storm petrels were seen. Sooty Shearwater was the dominant species. (See non-Grid Table #4 for summary of observations.)
