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

The width of the black 'tie' on the breast serves as a social signal; males with wider stripes are typically more dominant in the flock hierarchy.
During food-scarce winters, they have been observed as opportunistic predators, even preying on hibernating pipistrelle bats in caves.
They are renowned for their cognitive flexibility, famously learning to pierce foil milk bottle caps to reach the cream in the mid-20th century.
Great Tits are prolific cavity nesters and are one of the most successful species at utilizing artificial nest boxes in urban environments.
They are highly vocal with a repertoire of over 40 distinct calls, though the most recognizable is the rhythmic 'teacher-teacher' song.

Habitat

Deciduous and mixed woodlands, parks, gardens, and orchards.

Range

Widespread throughout Europe, North Africa, and across Asia to the Amur River.
