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 nearly identical to the Willow Tit but lacks the pale wing panel and has a glossier black cap.
The species is highly sedentary, with individuals often spending their entire lives within a few kilometers of their hatching site.
Despite its common name, it is rarely found in marshes, preferring mature broadleaf woodland and orchards.
It is a prolific food hoarder, caching thousands of seeds and insects during the autumn to survive the winter.
The most reliable identification feature is its explosive 'pitchou' call, which sounds like a sharp sneeze.

Habitat

Mature deciduous forests, parks, and gardens with a well-developed shrub layer.

Range

Temperate Europe and northern Asia.
