season north of the Southern Grid and apparently only a few stragglers are 
to be expected in the grid. 
Phoenix Island/Tahitian Petrel (2) 
These two species have been recorded in low numbers on several previous 
cruises. A Tahitian Petrel was collected in April and two Phoenix Islands 
Petrels were collected on Howland during the present survey. Both species 
can be expected to occur irregularly in small numbers in the grid area. 
Black-winged Petrel (78+9 nocturnal) 
This species was common in the grid during fall 1965 but was absent or 
very scarce during the period January-May 1966. None were noted in May. The 
buildup in numbers during the present cruise may represent "wintering" birds, 
but more likely these are migrating birds moving to areas north of the grid. 
Two specimens were collected. 
Bulwer* s Petrel (3+1 nocturnal) 
This species has always been recorded in low numbers except for an abundance 
of migrating birds in March 1966. Only one individual was recorded during 
May 1966. 
Whit e-throated Storm Petrel (2.) 
Two sightings were recorded during September 1965 with no records until 
May 1966. The few individuals found in the grid area are likely stragglers 
from the Phoenix Islands where the species is presently breeding®
