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.

Field notes

Rediscovered in 1984 after being known only from a single specimen collected in 1855.
It is locally revered as the 'Kacau ni Gau' and is a symbolic icon depicted on Fiji's 50-dollar note.
The population is extremely small, with current estimates suggesting fewer than 50 mature individuals remain.
It is highly nocturnal at its breeding sites to avoid predation by feral cats and pigs.
Fledglings are frequently disoriented by artificial lights, a phenomenon leading to 'grounding' in coastal villages.

Habitat

Pelagic open ocean and high-elevation, mossy primary rainforests on volcanic islands.

Range

Endemic to Gau Island, Fiji, with a foraging range extending into the surrounding South Pacific.
