AREA A: Total Birds- 19542 2512 3597 
Sooty Terns were the dominant species in Area A and accounted 
for 65.6 of total birds. Shearwater-petrels accounted for 26.7 
$> of total birds. The majority of shearwater-petrels were migrat¬ 
ing Sooty/ Slender-billed Shearwaters. Wedge-tailed Shearwaters 
were 2nd most abundant, with predominantly dark phase birds south 
of 6° N and light phase birds north of this latitude. Mottled 
Petrels were also encountered in low numbers. Practically all 
other groups were encountered in low numbers. Peak bird days were 
noted on 1 April north of Johnston Atoll and on 4 April between 
6 and 7° M. Feeding flocks composed primarily of Sooty Terns and 
Wedge-tailed Shearwaters were in abundance on both peak days.
