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¬ 
ments 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 ,r piece meal” fashion. This is unlike the SlenderbiU 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.

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.
