GRID SPECIES ACCOUNTS
Black-footed Albatross (Diomedea nigripes) 35 + 4 nocturnal
Density in both the north and central sections was lower than
that 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 individ-
uals 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 half 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 cookii.
Sightings were most common in the western half of the grid, espec-
ially on the north leg. Why 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
