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 is distinguished from the Greater Green Leafbird by its smaller size and the absence of a blue shoulder patch.
Males possess a black facial mask framed by a thin yellow border and a distinctive blue moustachial stripe.
Females lack the black mask and yellow throat of the male, appearing almost entirely lime-green with a faint blue malar line.
Its diet is omnivorous, consisting primarily of insects, spiders, nectar, and various forest fruits.
The species is highly sought after in the illegal cage bird trade, contributing to its status as Near Threatened.

Habitat

Lowland evergreen forests, secondary growth, and peat swamp forests.

Range

Malay Peninsula, Sumatra, Borneo, and extreme southern Thailand.
