Phase 3. Northern Grid to Honolulu . 
The third and last section of this report will deal with the 
observations made on the last leg of the cruise-the trip from the 
Northern grid area to Honolulu. This includes the diurnal observations 
of the 2l*th through the 27th of November and nocturnal watches for a 
few hours each on the 23rd and 2Uth of November. 
The general bird activity on it his portion of the cruise ranged from 
moderate on the 2l*th to low on the 26th and 27th. Shearwater-Petrels 
of various species were observed in fairly high numbers between 
approximatley 71-17N; 170-10W, and 18-53N; 165-10W. This area was 
cohered on the 21*th and 25th as we proceeded east-northeast of Johnston 
Island. Sooty Shearwaters were seen in high numbers on the 2l*th and 
Juan Fernandez Petrels were abundant on the 25th of November (see table). 
On the 26th and 27th, between 163 and 158 degrees west longitude, we 
were passing through a zone with few birds at this time of year. 
Flock activity was generally low throughout the journey back to 
Honolulu. The highest number of flocks seen on any one day was two. 
The majority of bird sightings were in singles or small groups (smaller 
tnan five). 
A brief account of each species observed during this portion of the 
cruise is as follows: 
Sooty/Slender-billed Shearwater : 
Ten birds identified as either Sooty Shearwater or Slender-billed 
Shearwater were sighted on the 2l*th of November traveling south as 
singles or in small groups ( see table). 
Sooty Shearwater: 
( Puffinus griseus ) 
Sooty Shearwaters werejobserved in moderate to relatively high 
numbers on the 2l*th and 25th of November, east-northeast of Johnston 
Island (see table). On the 2i*th the majority (86$) were traveling south 
although several were seen milling about or traveling in other directions 
(SE or SW). Approximately 25$ were positively identified as having light 
underwings on the 21*th. Many of the others were not viewed close 
enough to determine the underwing color. 
On the 25th, the numbers of Sooty Shearwaters observed dropped 
considerably (see table). One group of 10 biids was seen with a large 
mixed flock {feeding over tuna. The directional trend of these birds 
was again south. 
The vast majority of Sooty Shearwaters and all birds identified as 
Slender-billed Shearwaters/ or Sooty were observed west of 16510W. This 
fact, along with earlier eviden e, points to the probably late migration 
route of both species as being west of u ahu and p&ssibly west of the 
entire Leeward Chain. 
New Zealand Shearv:ater: 
( Puffinus bulleri ) 
One New Zealand Shearwater was observed flying south at annroximately 
169-13 W on the 2l*th. Two additional birds identified as probably this 
species were sighted on the 25th-one of them was headed south. This 
suggests that a few New Zealand Shearwaters pass through this area on 
their w*ay to their breeding grounds.
