Millions of Magellanic penguins live on the coasts of Argentina and Chile, but the species is classified as threatened, primarily due to the vulnerability of large breeding colonies to oil spills. The decline of fish populations is also responsible, as well as predators such as sea lions, giant petrels, and leopard seals which prey on the chicks. The warrah, before it became extinct, also preyed on the penguin.
Climate change has displaced fish populations, so Magellanic penguins must swim an extra 25 miles further from the nest for fish. While the penguins are swimming an extra 50 miles, their mates are sitting on a nest and starving.
