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 uniquely specialized for life in high-altitude mountain ranges of southwestern and central Europe.
Unlike many close relatives, it lacks heavy streaking on its back and flanks, possessing a smoother color profile.
Dietary studies show a strong preference for the seeds of the mountain pine (Pinus mugo) and various herbaceous plants.
Molecular phylogenetics led to its reclassification from the genus Serinus to Carduelis, showing it is more closely related to Goldfinches.
The species performs altitudinal migration, descending from peaks to lower valleys only when winter conditions become extreme.

Habitat

Subalpine coniferous woodlands and open alpine meadows near the treeline.

Range

Mountainous regions of Europe, including the Alps, Pyrenees, and Massif Central.
