this concentration is not considered a flock, but an area of concentration. 
Flocking of other species was noted rarely. Inactive groups of storm petrels 
or phalaropes were occasionally seen sitting on the water. Feeding flocks 
were noted only twice. The first (on 27 February) was composed of eight 
Black-legged Kittiwakes and a Pomarine Jaeger feeding over a natural slick 
about ten by fifty feet long. On the same day another flock composed of Gulls 
and Albatross which had been following the ship formed briefly over a group 
of feeding fish. A small slick formed at the same time. This flock dispersed 
in less than five minutes. 
Collecting during this survey was reduced from the last primarily 
because the outboard motor broke down. Fourteen specimens were shot from which 
eight blood sera samples were obtained,(see table 1.) 
For purposes of discussion the grid has been divided from both north to 
south (see table 2) and from east to west (see table 3)« These divisions are 
shown on map 2, 
Bathythermographs were taken on 39 localities within the grid on this cruise. 
G rid Species Accounts 
Black-footed Albatross (D iomedea n igrioes ) y* 
Highest densities were recorded in the central and southern sections of 
the grid with fairly even distribution from east to west. The distribution 
more closely approximates that of January as opposed to early February, 
probably due to differences in areas sampled during daylight hours. Two birds 
with bands were seen. 
Fulmar ( Fulmari s g lacialis ) 83 
Density was again highest in the northeast section of the grid with over 
sixty percent of the sightings being recorded in an area near point "D". The
