each census it is possible to calculate the percentage of the tagged 
adult group seen on any one census (Table 2). The mean percentage of 
tagged adult group seen during censuses is 9.2 (Sb 6.9) (see Figure 2). 
A chart was constructed to show the months in which, each individual was 
observed (Figure 3). From this chart it is possible to determine the 
number of different tagged individuals observed in each month. The mean 
number of different individuals observed for 22 consecutive months is 
(Sb 21.5). The mean percentage of the total tagged adult group

during a given month was used instead of the cumulative total of tagged 
seals to calculate on adjusted percentage of tagged seals observed on 
anP given census, with the assumption that only those seals seen at some 
time during the month composed the total population of tagged seals for 
that month (Figure 2). The mean adjusted percentage of tagged adult group
