Peter the Penguin Wades Ashore After 600-Mile Swim: In what is claimed to be the largest wildlife evacuation in history, 20,000 jackass penguins were removed from their island nesting places off the western Cape Horn in South Africa three weeks ago, trucked across the country and released to swim home. This gave environmentalists time to clean up the penguins’ habitat after it was fouled by an oil slick from a sunken ship. Almost exactly six years earlier, an oil leak from another sunken ship decimated the same penguin population; some of the currently rescued birds wear tags from the rescue effort six years ago.
