7-1-2016 HONG KONG - HAWAIIAN GOOSE (Branta sandvicensis)

The Hawaiian goose or the nene (Branta sandvicensis ) is the world's rarest goose. It is thought that the nene evolved from the Canada goose, which most likely arrived on the Hawaiian islands about 500,000 years ago, shortly after the island of Hawaiʻi was formed.

Adult male Hawaiian geese have a black head and hindneck, buff cheeks, and heavily furrowed neck. The neck has black and white diagonal stripes. Aside from being smaller, the female is similar to the male in coloration. The adult's bill, legs, and feet are black. It has soft feathers under its chin. Goslings resemble adults but are a duller brown and with less demarcation between the colors of the head and neck, and striping and barring effects are much reduced.

Native to the Hawaiian Islands, the Hawaiian goose today is found most commonly in Hawaii, in and around the Hawaii Volcanoes National Park, and on Maui in Haleakala National Park. A large and increasing population also lives on Kauai Island, and the animal has recently been reintroduced on Molokai Island. They don't migrate and inhabit various habitats, including scrub forests, grasslands, volcanic slopes with sparse vegetation, coastal dunes, and lava plains, and related anthropogenic habitats such as pasture and golf courses. Some populations migrated between lowland breeding grounds and montane foraging areas.
