Distribution and habitat

The subspecies is found on the beaches, pasture, rocky areas, and islands of the Recherche Archipelago, which is its only breeding site. It also visits Pink Lake and Red islet. The Cape Arid, Stokes, and Cape Le Grand National Parks are also occupied in summer months.

Behaviour

The geese feed by grazing and rarely swim. Nesting takes place mainly on the larger scrub-covered islands of the Archipelago, notably Cull Island.[3]

Status and conservation

Historically the population of the western subspecies was about 1000 individuals, declining in the early 1990s, with the current population considered stable. Its relative rarity of the subspecies makes it vulnerable to extinction.[4]
