Figure 1.
Spatial distribution of Sooty Shearwaters throughout the year.
Kernel density distribution of male and female Sooty Shearwaters from Kidney Island, Falkland Islands (star) during the pre-breeding period (i.e., prior to the pre-laying exodus; A,B), the pre-laying exodus (C, D), the incubation (E, F) and chick-rearing periods (G, H), and the period of non-breeding residence (I, J). Place names mentioned in the text are indicated.
Figure 2.
Foraging trip durations of Sooty Shearwaters during the pre-breeding and breeding periods.
Males are depicted in white and females in grey. Box plots show the median and 25th and 75th percentiles, whiskers indicate values within 1.5 times the interquartile range and circles represent outliers.
