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

The species was named after the prominent Russian ornithologist Valentin Bianchi.
It is nearly identical in plumage to Alström’s Warbler, necessitating song analysis for reliable field identification.
This warbler is primarily insectivorous, often seen hovering to glean small invertebrates from foliage.
Taxonomists split this species from the Seicercus burkii complex based on mitochondrial DNA and vocal differences.
It undergoes altitudinal migration, moving to lower elevations and more southerly latitudes during the winter.

Habitat

Dense broadleaf evergreen and deciduous montane forests, often with thick undergrowth.

Range

Breeds across central and southern China; winters in Indochina and parts of the Malay Peninsula.
