Cape Barren Goose, Adelaide Zoo
The Cape Barren Goose breeds on islands in Bass Strait Tasmania, as well as some islands in South Australia and Western Australia. In spring and summer large flocks disperse onto the mainland where they feed on grasslands and irrigated pastures.
While the total population is possibly no more than ten thousand, they can be locally present in large loose flocks. For example, about a twenty minute drive south of where I live I have seen a flock of about 500 feeding in one irrigated paddock. Only a few days ago I saw about 50 in the same area.
