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 was only formally described as a distinct species in 1995, having previously been overlooked as a subspecies of the Eurasian Treecreeper.
The species is a habitat specialist, almost exclusively found in old-growth forests dominated by large Faber's firs and dragon spruces.
Unlike many of its relatives, it lacks a distinct white eyebrow stripe and possesses a shorter, more strongly curved bill.
It is classified as Vulnerable due to its extremely small and fragmented population, which is restricted to a few isolated mountain peaks.
Genetic analysis indicates it is a relict species that diverged significantly from other Palearctic treecreepers during the Pleistocene.

Habitat

Mature subalpine coniferous forests between 2,500 and 3,800 meters elevation.

Range

Endemic to a restricted range within Sichuan Province, China, primarily in the Qionglai and Jiajin mountains.
