The Cape Barren or Pig Goose is one of the rarest geese in the world, found mostly in small islands

The Cape Barren or Pig Goose is one of the rarest geese in the world, found mostly in small islands off the coast of Australia. Their ability to drink salt or brackish water allows for large flocks to remain on the islands all year round. They have adapted to feeding on agricultural land, allowing for a reverse in the decline in numbers observed over the past century.
