A living page: each request adds its panels on top, every panel shows when it was added, and panels taken off are listed in the page history at the foot. Data: the 344 Palmer Archipelago penguins, 2007–08 to 2009–10.
Compared like for like, Adélie penguins weigh about the same on all three islands (averages within 21 g, intervals overlapping). Biscoe looked heavy only because the Gentoo live there.Adélie means by island with 95% bootstrap intervals; max − min = 21 g.
Gentoo are much heavier than the other two species, and males outweigh females in all three.Means with 95% percentile bootstrap intervals, 4000 resamples within species × sex.
About 110–120 penguins each season, all three species every time.
