The word “penguin”, some maintain, derives from Welsh pen gwyn (white head), a name allegedly bestowed by a Welsh sailor passing these shores with Thomas Cavendish in the sixteenth century. In fact, Magellanic penguins don’t have white heads and it’s far more likely that the name comes from the archaic Spanish pingüe, or fat. The birds were a gift to the early mariners, being the nearest equivalent at that time to a TV dinner.

Though they’re not exactly nimble on land, in water these birds can keep up a steady 8km an hour, or several times that over short bursts. An adult bird stands 50 to 60cm tall and weighs a plump 4–5.5kg. Birds begin arriving at their ancestral Patagonian nesting sites – which can be up to 1km from the sea – from late August, and by early October nesting is in full swing. Parents share the task of incubation, as they do the feeding of the brood once the eggs start to hatch, in early November. By early January, chicks that have not been preyed upon by sea birds, foxes or armadillos make their first sorties into the water. During the twenty-day February moult, the birds do not swim, as they lose their protective layer of waterproof insulation; at this time, penguin sites are awash with fuzzy down and sneezing birds. In March and April, they begin to vacate the nesting sites. Although little is known of their habits while at sea, scientists do know that the birds migrate north, reaching as far as the coast off Río de Janeíro, 3000km away.
