— Where the name comes from

Pygoscelis is Greek, pygḗ, “rump”, and skélos, “leg”: “legs set at the rump”, for the rear-placed legs that force it to stand upright. Adeliae comes from Adélie Land, the stretch of Antarctic coast that the French explorer Jules Dumont d’Urville named in 1840 after his wife, Adèle.

— What sets it apart

Stones are wealth. On the Antarctic coast suitable pebbles are scarce, and a raised nest keeps the eggs out of meltwater: penguins fight over them, steal them the moment a neighbour looks away, and the male brings them to his mate as a gift. Colony life shocked George Murray Levick, the doctor on Scott’s expedition, who in 1911 observed sexual behaviour he found so disturbing that he wrote it down in ancient Greek so that no one would read it. His account was found and published only a century later.
