This attractive goose is suspected to have suffered a moderately rapid decline, and it is thought to still be at risk owing to subsistence hunting and oil pollution. It is consequently classified as Near Threatened. Worryingly, it is expected to undergo a moderate population reduction in the near future owing to climate change.
