Once threatened primarily by oil spills, Magellanic penguins (Spheniscus magellanicus), now face a larger threat as fish are displaced by warming ocean currents, forcing the birds to swim farther to find food. Last year hundreds of Magellanic penguins washed up on beaches around Rio de Janeiro, many emaciated or dead.
Scientists have speculated that changes in ocean currents or temperatures, which may be related to climate change, could have been responsible for their movement more than a thousand miles north of their traditional nesting area in the southern tip of Argentina. Twelve out of the 17 penguin species are currently experiencing rapid population decline.
