How accurate is Birdsong's bird identifier?

It runs Google's Perch, a research-grade acoustic model covering nearly 15,000 species. When a call is ambiguous, we say so honestly and let you record a second clip to confirm, rather than guessing.

Is my recording stored?

No. Your audio is used to identify the bird in the moment and isn't saved to our servers. The birds you confirm are kept as cards in your own field journal; the recordings themselves are not.

Is the bird identifier free?

Yes — identify birds every day for free, no account required. Birdsong Pro ($3.99/mo or $39.99/yr) unlocks unlimited IDs, full field guides, your growing collection, and shareable Field Report cards.

Do I need an account or internet to identify a bird?

You'll need a connection to identify, since the AI runs in the cloud. No account is needed to try it — sign in with Google or email to save your field journal and sync it across devices.

Hawaiian Goose

Branta sandvicensis

The Nene is the world's rarest goose and the official state bird of Hawaii, uniquely adapted for terrestrial life on volcanic slopes. It is a descendant of the Canada Goose that evolved specialized morphological traits to thrive in island ecosystems.

What it sounds like

A soft, low-pitched 'nay-nay' sound from which its common name is derived, as well as louder honks similar to a Canada Goose.

Field notes

Possesses reduced webbing and elongated, padded toes to provide better grip when navigating rugged, jagged lava flows.
The species experienced a severe genetic bottleneck in the 1950s, with the global population dropping to approximately 30 individuals.
Unlike most waterfowl, Nene are capable of mating on land and do not require open water for any stage of their life cycle.
They exhibit a distinctive 'furrowed' neck feather pattern, where black feathers create deep, diagonal cream-colored grooves.
While they are capable of flight, they are non-migratory and spend their entire lives on the Hawaiian archipelago.

Habitat

Volcanic scrublands, grasslands, and sparsely vegetated lava plains from sea level up to high-elevation subalpine zones.

Range

Endemic to the Hawaiian Islands, primarily found on Hawaii, Maui, Kauai, and Molokai.
