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

Known locally as 'Tiê-sangue,' it is considered one of the most iconic birds of the Atlantic Forest biome.
Males possess a unique 'chalky' white base on the lower mandible, which contrasts sharply with their otherwise black bills.
The species displays extreme sexual dimorphism; while males are brilliant scarlet, females are a more cryptic greyish-brown.
It is primarily frugivorous, frequently visiting bird feeders and fruit trees in urban gardens and coastal areas.
Nests are typically cup-shaped structures built in dense shrubs, where the female lays greenish-blue eggs with dark spots.

Habitat

Coastal scrub (restinga), secondary growth, forest edges, and urban gardens.

Range

Endemic to eastern Brazil, ranging from Paraíba south to Santa Catarina.
