(Redirected from Nēnē)
The 'Hawaiian Goose' or 'Nēnē', ''Branta sandvicensis'', is a
species of
goose endemic to the
Hawaiian Islands. It shares a recent common ancestor with ''Branta canadensis'', the
Canada Goose. The official bird of the
State of Hawaiii, the Nēnē is exclusively found in the wild of the islands of
Maui,
Kauai and
Hawaii. A larger, extinct and possibly flightless species, the
Nēnē-nui (''Branta hylobadistes'') was present in prehistoric times on Maui; related, but hitherto undescribed forms also occurred on Kauai and
Oahu, and there was a gigantic, flightless relative on the island of Hawaii.
The Nēnē gets its
Hawaiian name from its soft call.
The species has a black head, buff cheeks and heavily furrowed neck. Bill, legs and feet are black. The young birds are as the male but duller brown and with less demarcation between the colors of the head and neck, and striping and barring effects are much reduced. Bill, legs and feet as for the adult.
The female Hawaiian Goose is similar to the male in coloring but slightly smaller.
Its strong toes have much reduced webbing, an adaptation to the lava flows on which it breeds. It mates on land unlike most other wildfowl.
This is the world's rarest goose. Once common, hunting and introduced predators such as
mongooses,
pigs, and
cats reduced the population to 30 birds by 1952. However, this species breeds well in captivity, and has been successfully re-introduced so in 2004 it was estimated that there were 500 birds in the wild (and good numbers in wildfowl collections). However, there is some concern of inbreeding due to the small population of birds. The nature reserve
WWT Slimbridge in
England was instrumental in the successful breeding of Nēnē geese in captivity, under the direction of the leading conservationist Sir
Peter Scott, during the 1950s, for later re-introduction into the wild in Hawaii. There are still Nene geese at Slimbridge today.
