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 considered a subspecies of the Japanese Robin but is now recognized as a distinct species due to genetic and morphological differences.
Adult males lack the distinct black border between the orange throat and gray breast that is characteristic of the mainland Japanese Robin.
The species possesses a notably longer bill and larger body mass compared to Larvivora akahige, likely an adaptation to island ecology.
It is classified as Near Threatened due to its restricted range and vulnerability to habitat degradation and invasive species.
During the breeding season, it is highly territorial and primarily forages within the dense leaf litter of the forest floor.

Habitat

Undergrowth of primary and secondary broadleaf evergreen forests and temperate deciduous woodlands.

Range

Endemic to the Izu Islands of Japan, including Oshima, Miyakejima, Mikurajima, and Hachijojima.
