Pink-footed Shearwater 3 One bird was seen on 29 September in Sector 2, and two birds were recorded 1 October in Sector 6. Sooty Shearwater 100 During this and the last survey Sooty Shearwaters have been moving through the grid area. The general movement is toward the southwest. A few birds seen in the western section of the northern and central sections are moving south. These birds may join the south-western "stream" of birds or may represent a separate movement. The move- mements around Point Conception where there are concentrations of the birds show the southwest movement but there is a possible funneling of birds to this area as though it were a jumping off point for migration. That there are still large numbers of sooties north of Point Conception at this time and that we have not recorded great concen- trations in migration, suggests that this migration occurs slowly in a "piece meal" fashion. This is unlike the Slenderbill Shearwater migrations in the Central Pacific where we have massive flocks moving fast through the area. Sooty Shearwaters have been recorded sitting on the water in the grid during the past two surveys. Leach's (type) Storm Petrel White-rumped Storm Petrels 147 Dark-rumped Storm Petrels 4 Storm Petrel sp. 40 191 Numbers have increased over the last survey. Many of the birds recorded during this survey were moving north. This movement was direct and rapid and is undoubtedly a migration. There was an increased population of these south-moving birds with brilliant white rumps. This strongly suggests that the birds moving south through the area at this time are birds from northern breeding populations rather than a final southward movement of southern birds that moved northward through the area on earlier surveys this summer. Black Petrel 3 Again on this survey as on Eastern Grid Survey 13, a few birds of this species were recorded.
