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

Commonly known in Brazil as the 'Curió', it is one of the most highly prized songbirds in South America for its vocal capabilities.
The species was formerly classified in the genus Oryzoborus before molecular data moved it into the Sporophila seedeater group.
Males possess a distinctive deep-black plumage with a rich chestnut-colored belly and a small white patch on the wing.
They have an exceptionally thick, heavy beak adapted specifically for crushing hard seeds and grains.
This species is a frequent target of the illegal wildlife trade due to its popularity in competitive bird-singing contests.

Habitat

Open shrublands, forest edges, marshes, and tall grasslands.

Range

Widespread throughout South America, including Brazil, Colombia, Venezuela, and northern Argentina.
