leach’s Storm Petrel (10) 
All 10 birds accorded to this species were collected specimens. 
Undoubtedly the vast majority of the 106 unidentified white-rumped storm 
petrels recorded are referable to this species. However, low numbers of 
Harcourt’s and Wilson’s Storm Petrels have been collected in the Grid 
during previous cruises and may represent a small percentage of the 
unidentified birds. These two latter species were not collected during 
the present cruise. White-rumped storm petrels were first encountered in 
modest numbers during the October 1965 cruise and had increased greatly by 
November to the approximate present numbers. The Grid apparently serves 
as a "wintering" area for Leach’s Storm Petrel. 
Red-tailed Tropicbird (2) 
This species has been represented by very low numbers during all 
previous cruises. One individual, banded at Enderbury Island, was collected 
in the Grid. This further enlarges the list of species from the Phoenix 
group which utilize the Grid area. 
White-tailed Tropicbird (4) 
Considerably greater numbers of this species were recorded during the 
October and November-Lecember cruises. Numbers of this far-ranging species 
can probably be expected to fluctuate considerably in the Grid Area. 
Blue-faced Booby (33 + 5 nocturnal) 
Numbers were comparable to previous cruises. The majority of birds 
were sighted on 5 and 7 February in close proximity to Howland-Baker. One 
collected individual had been banded on Enderbury Island. This represents 
the fourth specimen taken in the Grid from that island. 
Brown Booby (3) 
The same low number was recorded during the November-Lecember Cruise. 
Greater numbers were recorded during September and October. Grid sightings 
are most likely Howland based birds.
