One bird was well-observed on January 20 in the northern area

Sooty Shearwater 2 
( Puf.finus g riseus ) 
Slender-oilled Shearwater 1 
( Puffirms tenvirostris ) 
Sooty/Slender-billed (unidentified) 3 
Two sooties and one slender-billed were identified in the central 
third of the grid. In addition three unidentified sooty/slender-billed 
shearwaters were recorded in the northern section. 
White-winged Petrel 1 
( Pterodroma leucoptera ) 
Pterodroma sp.? (either P. cookii or P. leucoptera ) 
To date members of this genus were only suspected to occur off 
the west coast of North America, and to date there have been no 
known collections. However one bird well-observed during this survey 
was quite definitely P. leucoptera . This bird, seen at close range, 
was a dark-phase type with a white neck and throat. It was, however, 
unlike the dark-phase birds s^en in the central Pacific in that the 
underwing had a white central area bordered with black. 
Seven additional small Pterodroma were noted but not identified 
to species. It is believed, however, that none of those seen well 
(5) were hypoleuc a. Some had very light underwings suggesting P. 
cookii or P. leucoptera masafuerae , but no positive identification 
could be made. 
Herald Petrel 1 
( Pterodroma heraldica ) 
One dark-phase cird of this species was identified after being 
w T ell~observed for five minutes. It should be considered accidental 
to the northeastern Pacific. 
Fork-tailed Petrel 13 
( Oceanodroma furcata ) 
All sightings were of birds in the northern and central portions 
of the grid. Sub-specific identifications will have to await represent¬ 
ative collections.
