    I counted 49 adults and only 20 chicks here. It is not the ratio I was expecting, although I know that some chicks are just obscured..

    We know 3 didn't make it- The lower right corner nest had 2 eggs but raised only 1 chick.

    The nest just slightly up and left of the corner nest always has a territory conflict. Their 2 chicks died in some of the scuffles.

    It has seemed to me quite a few nests here have single chicks. Perhaps someone has kept a close count for this site?

    @yshish- I wonder if this explains the chick/adult numbers: "Gentoo penguin populations are characterised by large annual fluctuations..."

    "... in population size and breeding success with the later ranging between 0.5 and 1.5 chicks fledged per breeding pair." http://www.penguins.cl/gentoo-penguins.htm
