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

Possesses a broad-based bill with a distinct downward kink at the tip, adapted for specialized tactile foraging in soft substrates.
Exhibits a unique head pattern where the white supercilium splits into two distinct branches, creating a double-striped appearance.
While now categorized in the genus Calidris, it was historically placed in its own monotypic genus, Limicola, due to its morphological divergence.
Breeding behavior is notably secretive, with nests typically well-concealed in deep vegetation atop wet peat hummocks.
It is a long-distance migrant, with some populations traversing the Central Asian Flyway to reach wintering grounds in Australasia.

Habitat

Breeds in subarctic wet mires and blanket bogs; winters on coastal mudflats, estuaries, and inland salt pans.

Range

Breeds across Northern Europe and Siberia; winters in East Africa, Southern Asia, and Australasia.
