The southern sea penguins in this App inhabit from the Heard & McDonald Islands (≈ 73.5° E) in the Southern Indian Ocean — the world’s only uninhabited islands ever to have tariffs imposed on their “exports” of guano and feathers — around to South Georgia (≈ 36.5° W) in the Southern Atlantic, spanning over 7 000 km (3 800 nautical miles) of Southern Ocean.
Note: The collective wisdom of The Southern Chorus may yet prove more than ornamental — offering clarity of thought, noise-free communications, and unparalleled opportunities for independent commentary.
