Distribution and habitat
editThe 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
editThe 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
editHistorically 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]
