Fig. 5. Behavioral budget for Milford Sound (MS) and Doubtful Sound (DS) depending on boat presence. Budgets are given as the proportion of time spent in a given state (sum = 1 across states). Error bars are 95% confidence interval. The significance of the difference between each effect (location and boat impact) is given for each behavioral state above the bars (z-ratio statistic, Fleiss 1981). * = p < 0.05, ** = p < 0.001, *** = p < 0.0001. TR stands for traveling; REST, resting; MI, milling; DIVE, diving; and SO, socializing.
