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 was historically treated as a subspecies of the Madagascar White-eye before being elevated to full species status based on morphological differences.
The distinctive white ring around its eye is not skin, but a circle of specialized tiny feathers.
It is primarily found at higher elevations, rarely occurring in coastal lowland areas.
The species is highly social and typically forages in small, active flocks moving quickly through the canopy.
It is currently classified as Vulnerable due to its extremely small range and the continuing loss of native forest habitat.

Habitat

Primary humid montane forests, secondary forests, and occasionally modified habitats like plantations.

Range

Endemic to the island of Anjouan (Ndzuani) in the Comoros archipelago.
