Breeding colonies of the emperor penguin Aptenodytes forsteri are distributed throughout the Antarctic seasonal pack ice zone. One of the last colonies of emperors penguins discovered is situated on the south coast of Snow Hill Island, constituting the northernmost colony known in Antarctica. We conducted a census of adult individuals using aerial photographs taken from an aircraft flight over the colony during the 2013 breeding season. Likewise, we explored the colony by land, making an estimated counting of the number of chicks. From the previous census, the colony exhibited a population increase.
