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 only wood-rail in its range that lacks any rufous or chestnut coloration on the breast and belly.
Pairs are known for performing loud, synchronized vocal duets, often during the twilight hours of dawn and dusk.
The species possesses striking red legs and irises, contrasting with a greenish bill that has a reddish base.
While it frequents swampy areas, it is more terrestrial than many rails, often foraging on the forest floor far from standing water.
Its scientific and common names are derived from 'Saracura,' the indigenous Tupi-Guarani term for various rail species.

Habitat

Humid forests, forest edges, and marshy areas near streams or wooded swamps.

Range

Southeastern Brazil, eastern Paraguay, and northeastern Argentina.
