SPECIES ACCOUNTS 
Wedge-tailed Shearwater (12+4 nocturnal) 
During the three previous cruises this species has consistently been 
one of the most abundant procellarids. During previous cruises, the vast 
majority of sightings have been dark phase southern hemisphere birds. 
During the present cruise only two of nine recorded as to color phase were 
dark. Apparently southern breeding birds have moved out of the area and 
only a few stragglers from northern breeding areas are present. Large 
numbers of dark phase birds were noted on 3 February north of the grid 
area (between 5 and 6 degrees N) 
Audubon's Shearwater (2+6 Nocturnal) 
This species has been observed irregularly in very low numbers since 
September. Probably a few stragglers from the Phoenix Islands account for 
its presence in the Grid. 
Juan Fernandez Petrel (2) 
This species was recorded in low numbers during the November-December 
survey but not during September or October. Apparently a few birds migrate 
through the Grid, but there is no indication as yet that large numbers of 
this species utilize the area. 
Bulwer f s Petrel (10) 
This species was recorded in low number's during every survey period 
from September 1965 to the present. One specimen was collected. 
Phoenix Island / Tahitian Petrel 
Only a few individuals referable to these two very similar species 
have been recorded in the Grid thus far. Most likely these are Phoenix 
Island Petrels from breeding areas in the Line Islands or Phoenix group.
