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 displays strong sexual dimorphism, with males being bright turquoise-blue and females appearing primarily olive-green.
The primary field mark distinguishing it from the similar Blue Dacnis is its blackish legs, rather than pink or flesh-colored ones.
It is a canopy specialist, frequently joining mixed-species foraging flocks alongside other tanagers and honeycreepers.
The species is classified as Near Threatened due to ongoing habitat loss and fragmentation within its restricted range.
Its diet is opportunistic, consisting of a mix of small fruits, nectar from flowers, and arthropods gleaned from foliage.

Habitat

Primary and secondary humid evergreen forests, predominantly in the canopy and forest edges.

Range

Endemic to the Atlantic Forest of southeastern Brazil, ranging from Espírito Santo south to Rio Grande do Sul.
