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

Distinguishable from the similar Rook by its heavier black bill and lacks the bare grey skin at the bill base.
Known to utilize 'tool-like' behavior, such as dropping hard-shelled nuts onto roads for cars to crack open.
Possesses the cognitive ability to recognize individual human faces and remember them for several years.
Forms socially monogamous pair bonds that often persist for life, maintaining territories year-round.
Commonly hybridizes with the Hooded Crow (Corvus cornix) in a narrow zone where their ranges meet.

Habitat

Open countryside, agricultural land, woodland edges, urban parks, and coastal cliffs.

Range

Western Europe and East Asia, separated by the range of the Hooded Crow.
