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

It belonged to the Mohoidae family, which represents the only modern extinction of an entire avian family.
The species was highly specialized for nectarivory, particularly favoring the long, tubular flowers of native lobelioids.
Its plumage was historically prized by Hawaiian nobility for use in creating elaborate feather capes and leis.
Sexual dimorphism was present, with males being significantly larger than females and possessing longer, more decurved bills.
The last confirmed sighting occurred in 1904 by George Munro, though unconfirmed reports on Maui persisted until the 1980s.

Habitat

Dense montane rainforests and high-altitude plateau forests.

Range

Endemic to the island of Moloka'i, Hawaii.
