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.

Azure-shouldered Tanager

Thraupis cyanoptera

Field notes

It is noticeably larger and possesses a heavier, more robust bill than the similar and more common Sayaca Tanager.
The 'azure' shoulders are technically the lesser wing coverts, which contrast against a paler, dusty-blue body.
Primarily frugivorous, it plays a vital role in its ecosystem by dispersing seeds of native Atlantic Forest trees.
It is a frequent participant in mixed-species foraging flocks, often traveling with other tanagers and honeycreepers.
The species is largely restricted to the Atlantic Forest biome, making it sensitive to habitat fragmentation and deforestation.

Habitat

Canopy and edges of humid montane and lowland forests, as well as mature secondary growth.

Range

Southeastern Brazil (Espírito Santo to Rio Grande do Sul), eastern Paraguay, and northeastern Argentina.
