V/edge-tails accounted for 12$ of the Shearwater-petrel observations and 
were second in abundance to the Slender-billed Shearwater. Thirty-one per 
cent of the non-Slenderbill Shearwater-Petrels were Wedge-tails. In the 
vicinity of 8 °N., 178 E., on 15 November, both color phases were present 
in relatively equal numbers. This broad zone of color phase overlao is 
not noted as strongly in the usual N-S transect further to the east. In 
December the clear disjunction of the color phase populations occurred roughly 
at 9°N (167 W). 
Sooty Shearwater Total -32 
(Puffinus griseus ) 
Lingering Sooty Shearwaters were generally seen either in association 
with Slender-bills in the higher latitudes or alone between Samoa and the 
Phoenix Islands. The high density in the southern area was also noted 
in the September-October survey. 
Slender-billed Shearwater Total -2,996 
(Puffinus tenuirostris ) 
The high number observed in the first week of November 15 evidently a 
tertiary migration peak. Two poorly defined peaks were noted in the first 
and third weeks of October (see previous non-grid report). On 6 November, 
2,578 birds ( 86 $ of the species total) were recorded. The average flock size 
this day was U5«
