In this simplification only four symbols are used to describe the dis¬ 
tribution: 
* 
0 = No bird(s) ji.£., linear density 0.000 
_ = Bird(s) present but at low density as compared to the 
overall 
1 = Bird(s) present in ’’about the same” density as the overall 
+ = Bird(s) present at high relative density. 
(Solution ”D” interprets ’’about the same” as being a single digit in 
Solution ”C”.) 
Perhaps the best lesson learned from this exercise is the relatively 
inconsistent results obtained by not having the ’’correct” number of com¬ 
parable subdivisions. Clearly, a single bisector has limited value on 
this particular Grid. The three north-to-south sections are better, but 
when compared alone are not nearly as effective as when divided by the 
north-to-south bisector and compared as six equal subdivisions. While six 
divisions is a fairly good number for the size of this Grid area, I feel 
that nine subdivisions would yield somewhat more useful information (see 
Figure #4). In the species accounts that follow the distribution patterns 
are indicated by six characters arranged according to Solution ”D.” These 
representations apply only to track data.

Albatross numbers are reported as the maximum seen during the day. 
From 3-19 birds were seen during the survey (mean 8.5/hay, median = 7)- 
Of 4l birds with rump color recorded, 15 (32$) were white-rumped. Nine¬ 
teen birds were seen on 23 and 26 July in similarly high concentrations 
of Storm Petrels. At Point Dogwood, 42 miles from shore, 19 birds were 
seen, but later the same day, 11-20 miles from land (Pt. Conception), 
only three were present; Storm Petrels were absent at that distance from 
land (see Non-Grid Section ”C”). About two-thirds of the albatrosses were 
seen in the eastern half.
