A new survey has found Adélie penguin numbers in East Antarctica to be nearly six million, double previous estimates. Past surveys have been based only on breeding pairs, so the increase could be attributed at least partly to counting non-breeding penguins, which tend to be out foraging at sea. While the news of the large Adélie population may be cause for celebration, scientists warn that shrinking ice and warming waters could threaten penguin habitat and prey availability in the long term.

Read more about the latest survey and why it may be cause for both celebration and concern.
