GRID SPECIES ACCOUNTS 
Black-footed Albatross 
( Diomedea niqripes) 
35+4 nocturnal 
Density in both the north and central sections was lower than 
chat recorded on the last survey. East-west differences were not 
as marked as in early April, but were still evident. 
An attempt was made to keep track of unusually marked inaivid 
us 1s to determine how long they followed the ship. On 21 April 
two birds were followed closely; one followed about six hours and 
another for at least thirteen hours. On the 22nd another bird was 
recorded for more than ten hours. 
The numbers of birds with dark upper tail coverts outnumbered 
those with white or mostly white by 5:1. 
Laysan Albatross ( Diomedea immutabilis ) 1 
One bird with an unusually pink bill was recorded in the 
eastern l^alf of the central section. 
Fulmar ( Fulmarus glacialis) 0 
This is the first eastern grid survey to date on which no 
Fulmar were seen. 
Small Pterodroma (Not positively identified) 50 
Judging by the field marks of the small Pterodroma which were 
well observed, it is felt that virtually all were Pterodroma c ookii . 
Sightings were most common in the western half of the grid, espec¬ 
ially on the north leg. 'Afhy an equal number was not seen to the 
south at equivalent longitudes is puzzling. A noticeable decline 
was recorded between points B and C; thereafter sightings were 
relatively scarce. 
Most of those birds for which direction of travel was noted
