The Cape Barren goose, sometimes also known as the pig goose, is a species of goose endemic from southern Australia. It is a distinctive large, grey bird that is mostly terrestrial and is not closely related to other extant members of the subfamily Anserinae.
Region
Southern Australia
Typical Environment
Occurs on offshore islands and coastal fringes of southern Australia, especially the Bass Strait islands, Tasmania, Kangaroo Island, and parts of South Australia and Western Australia (e.g., Recherche Archipelago). Prefers open tussock grasslands, coastal dunes, and agricultural pastures, often far from permanent freshwater. Frequently uses small islets for breeding and nearby mainland or larger islands for post-breeding grazing. It is largely coastal but may move inland to open paddocks outside the breeding season.

This distinctive goose is named for Cape Barren Island in Bass Strait and is one of the few waterfowl that regularly graze far from water. It has a lime-green cere over the bill and utters grunting, pig-like calls, which earned it the nickname 'pig goose.' Largely terrestrial, it can drink brackish water and is placed in its own genus, reflecting its unique lineage among geese.
Temperament
generally wary; territorial during breeding
Flight Pattern
strong, direct flier; reluctant to fly unless disturbed
Social Behavior
Monogamous pairs nest on the ground among tussock or low shrubs, building substantial nests of vegetation. Outside the breeding season they form loose flocks that graze together in open fields. Parents are attentive and can be aggressive when defending nests or goslings.
Migratory Pattern
Partial migrant
Song Description
Vocalizations include deep grunts and pig-like snorts, along with low honks used for contact. Alarm calls are harsher and more rapid, especially near the nest.
