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 largest species within the genus Curruca, reaching a length of up to 17 centimeters.
Adults possess a distinctive bright yellow iris, which is significantly duller or brownish in juvenile birds.
They often engage in a symbiotic nesting association, frequently building nests near Red-backed Shrikes to benefit from their aggressive territorial defense.
The species is a long-distance migrant, with populations traveling from the Palearctic to wintering grounds in East Africa.
While primarily insectivorous during the summer, they shift their diet significantly toward berries and small fruits during autumn migration.

Habitat

Dense thorny scrub, thickets, forest edges, and bushy wasteland.

Range

Breeds across Central and Eastern Europe to Western China; winters in East Africa.
