How many penguins are there, total ?
Many parts of Antarctica, including some of the shores, have never been explored, so the precise number of penguins is unknown. Evaluations have been done by counting manually the penguin population in some areas and extrapolating to the entire continent. The numbers of 2 300 000 pairs of Adelie Penguin and 220 000 pairs of Emperor Penguin have been proposed by some researchers. But keep in mind that those are highly inaccurate statistics, most colonies not having been visited in decades, and many more having never received a visit. Also some estimates have been performed at the wrong time of year or not from manual counts (based on aerial photographs for instance).
