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 species is currently classified as Critically Endangered due to heavy exploitation by the illegal cage bird trade.
Unlike its close relatives, the Javan Leafbird lacks blue coloration in its wing feathers, appearing almost entirely green and yellow.
Males display a striking black face and throat patch bordered by yellow, while females are largely green with a smaller yellow throat wash.
They possess a specialized brush-tipped tongue, which is an evolutionary adaptation for feeding on nectar from forest blossoms.
Their population has declined so sharply that they are now more common in captivity than in their remaining native forest fragments.

Habitat

Subtropical or tropical moist lowland and montane evergreen forests.

Range

Java, Indonesia.
