    The chicken-loving dog spent last month guarding the island’s penguin colony, with great success.

A SOUTH-WEST Victorian chicken farmer known as Swampy and his dog Oddball may have found a way to save some of Australia’s endangered wildlife from enemies. After Warrnambool’s once flourishing penguin population was killed in large numbers by foxes and dogs until only 27 remained, Allan Swampy Marsh hatched an effective plan to save the birds. His four sheepdogs had been protecting his chickens against enemies for a decade. He figured they could do the same for the penguins. “The difficulty was trying to convince all the wildlife wallies to think outside the square,” Mr Marsh said. “It’s not an unselfish view of penguins or chicks but the sense of territory (领地) that makes the dogs work, and it is far stronger in these dogs than any other trained breed.”

Oddball’s work as guardian of Middle Island’s colony last month was a success. At the end of the month, 70 pairs of happy feet were counted returning to the island. About 2,000 penguins occupied the island in the 1990s. “Oddy is really protective of the chicks, so to her the penguins were only chicks in dinner suits,” Mr Marsh said. Highly territorial dogs have been bred in Italy to guard livestock for 2,000 years. They manage to keep off trouble makers such as foxes and dogs. The trial’s success has generated interest from overseas. The use of guard animals such as dogs — and even alpacas, which also stop foxes — is now being considered to save other endangered species such as the eastern barred bandicoot.
