Fiordland penguins (Eudyptes pachyrhynchus), known as Tawaki, travel between 3,500 and 6,800 km over the course of 69 days in search of a hearty meal after having gone hungry for weeks while nurturing hatchlings. Researchers tagged the birds with satellite transmitters and tracked their movements from their breeding ground on the South Island’s west coast to one of two feeding grounds (one to the south of Tasmania and another just north of the Antarctic), and back. The findings were published August 29 in PLOS ONE.
