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 features a distinctive dark chocolate-brown cap and bib, contrasting with its buffy-brown flanks and grayish-brown wings.
Formerly classified as a subspecies of the Willow Tit or Sombre Tit, it is now widely recognized as a distinct species.
The species is a sedentary resident, remaining in its mountain forest territory throughout the year regardless of seasonal changes.
It is a primary cavity nester, often excavating its own nesting hole in the soft, decaying wood of deciduous trees.
Its population is strictly tied to the ancient Hyrcanian forest ecosystem, making it vulnerable to local habitat loss.

Habitat

Montane deciduous forests, particularly those dominated by oak, hornbeam, and beech.

Range

The Alborz Mountains of northern Iran and the Talysh Mountains of southeastern Azerbaijan.
