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 is the national bird of Finland and is featured on the Finnish 1-euro coin.
The yellow pattern on each bird's bill is unique, allowing researchers to identify individual swans in the field.
They are capable of flying at extreme altitudes during migration, with radar records documenting them at nearly 27,000 feet.
Unlike the Mute Swan, the Whooper Swan carries its neck straight and lacks a black basal knob on the bill.
Pairs typically form lifelong monogamous bonds and migrate together with their offspring during the first winter.

Habitat

Breeds in shallow freshwater pools, marshes, and taiga lakes; winters in coastal bays, estuaries, and agricultural fields.

Range

Northern Eurasia, breeding from Iceland across Russia to the Pacific; winters in Europe, East Asia, and the Caspian region.
