Laysan Albatross is here statistically treated like the other birds
whereas Black-footed Albatross is again eliminated from the regular
tables.
Black-footed Albatross
Diomedea nigripes
Total # Obs. = 31
Avg. #/day = 3.8
Median of 8 days = 4
High max. day count = 7
Low max. day count = 2
Of the 28 birds with rump color noted only one was sharp white; the
remainder were all dark. Numbers have increased slightly over the low
point reached on the last survey. There appears to be a tendency for
higher numbers in the southwest.
Fulmar
Fulmarus glacialis
# Obs. = 1
The virtual absence of Fulmars in the Grid was very unexpected.
Sooty Shearwater
Puffinus griseus
# Obs. = 204
After the abrupt southeast migration peak in mid-September a period
of about a month passed wherein Sooty numbers over the coastal area were
low. Through the November surveys, however, another influx of southward-
moving birds has been noted. This secondary migration is on a broader
front and less concentrated than the first. Unlike the well-defined
east-southeast direction in September, the present movement is due south.
One collected bird was an immature male and suggests the possibility that
the present movement is of immature and non-prebreeding birds, whereas
the September peak may have been prebreeding adults.
Pale-footed Shearwater
Puffinus carneipes
# Obs. = 2
The second and third records for the Grid area. Both were seen in
Section W.
New Zealand Shearwater
Puffinus bulleri
# Obs. = 1
The single bird was seen heading northeast in Section Y.
Small Pterodroma
# Obs. = 4
The three sightings scattered over the Grid were possibly referable
to P. cooki.
