The Hawaiian name nēnē comes from its soft call. The specific name sandvicensis refers to the Sandwich Islands, a former name for the Hawaiian Islands. The holotype specimen of Anser sandvicensis Vigors is held in the vertebrate zoology collection at World Museum, National Museums Liverpool, with accession number NML-VZ T12706. The specimen was collected from the Sandwich Islands (Hawaiian Islands) and came to the Liverpool national collection via the Museum of the Zoological Society of London collection, Thomas Campbell Eyton's collection, and Henry Baker Tristram's collection.
It is thought that the nene evolved from the Canada goose (Branta canadensis), which most likely arrived on the Hawaiian islands about 500,000 years ago, shortly after the island of Hawaiʻi was formed. The Canada goose is also the ancestor of the prehistoric giant Hawaiʻi goose (Branta rhuax...

Possible
About 30% of wildlife watchers report a Hawaiian Goose sighting in Hawaii Volcanoes National Park on a given day, based on 822 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 29 birds we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
January, August and October–November
In those months about 50% of wildlife watchers report a Hawaiian Goose in Hawaii Volcanoes National Park on a given day, against about 10% in April, the lowest month.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Hawaiian Goose sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Hawaiian Goose sightings, Hawaii Volcanoes National Park ranks 3rd at about 30%. The best odds are in Kilauea Point National Wildlife Refuge (United States, about 90%) and Haleakala National Park (United States, about 50%).
GBIF citizen-science records
It is estimated from how often the Hawaiian Goose is recorded against all the birds logged in Hawaii Volcanoes National Park (822 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
