8 In this simplification only four symbols are used to describe the dis- tribution: 0 = No bird(s) i.e., linear density 0.000 _ = Bird(s) present but at low density as compared to the overall l = 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-toece- 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. SPECIES ACCOUNTS Black-footed Albatross (Diomedea nigripes) # Obs. Track Nontrack Total 66 27 93 + 1 1 1 - 1 Albatross numbers are reported as the maximum seen during the day. From 3-19 birds were seen during the survey (mean 8.5/day, median = 7). Of 41 birds with rump color recorded, 15 (32%) were white-rumped. Nine- teem 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.
