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 often cited as the bird with the fewest identifying features, possessing no eye-stripes, wing bars, or prominent crown colors.
During late summer, it switches from an insectivorous diet to eating berries to build fat reserves for migration.
It is a long-distance migrant, traveling thousands of miles between European breeding grounds and sub-Saharan African wintering sites.
The song is a fast, musical warble that is frequently confused with the Blackcap but is typically longer and more even in pitch.
Despite its name, it is more frequently found in woodland glades and thick brambles than in typical suburban gardens.

Habitat

Dense deciduous thickets, woodland edges, and overgrown scrub with heavy cover.

Range

Breeds across Europe and Western Siberia; winters in sub-Saharan Africa.
