Fig. 4. Changes in dive parameters associated with each molt stage (illustrated along the x axis). The first (leftmost) point in each series is the overall mean from all birds for molt stages 0 and/or 5. The following points represent average deviations from that baseline mean. See text for details. Sample sizes (number of birds) are shown in C, with further details in Table 1. Error bars represent 95% confidence intervals. Lowercase letters indicate the results from Tukey-Kramer multiple comparisons tests; means that have a lowercase letter in common are not significantly different (=0.05). If no letters are present then none of the means differ significantly.
