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.

The species possesses a unique bare patch of pinkish-white skin at the base of its large, pale bill.
They are colony nesters where a single alpha male typically mates with most of the females in the group.
