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

Formerly classified in the genus Sylvia, it was moved to Curruca following molecular phylogenetic studies.
It possesses a distinct white eye-ring and fine dark streaking on the throat that is visible at close range.
The species is highly active and restless, frequently cocking and fanning its tail while foraging through thorny thickets.
While primarily insectivorous, it is known to supplement its diet with small fruits, berries, and occasionally nectar.
It is a monogamous breeder that constructs a thin-walled, cup-shaped nest usually hidden deep within a thorny acacia.

Habitat

Dry acacia savanna, arid scrublands, and suburban gardens.

Range

Southern Africa, including South Africa, Namibia, Botswana, and Zimbabwe.
