huge numbers of migrating Sooty/Slender-billed Shearwaters. Practically all 
were seen on lk and 15 September just north of the Howland-Baker Area. Both 
Sooty Terns and Wedge-tailed Shearwaters were also abundant throughout Area a.; 
the greatest numbers were encountered in mixed feeding flocks. 
Area b. was dominated by terns, boobies, and frigatebirds; Procellarids were 
relatively very low in number. The majority of birds were accounted for on 
three peak days: 29 September, just south of Hull Island; 3 October, just south 
of Enderbury and on 11 October near Tutuila, Samoa. One immense feeding flock 
just south of Enderbury on 3 October accounted for nearly half of the birds seen 
throughout Area b. 
Area c. showed fairly consistent medium to high daily totals. The Sooty/ 
Slender-billed Shearwater migration had passed and only a few stragglers showed 
during this phase of the cruise. Terns accounted for roughly two thirds of the 
total. Procellarids were common with a diversity of species. Wedge-tailed 
Shearwaters was the most abundant species in this group.
