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 a specialist of Várzea forests, specifically inhabiting seasonally flooded areas and mature river islands.
The bright yellow crown patch is often held flat and hidden, becoming visible only during territorial displays or agitation.
It possesses two distinct pale wing bars and a thin, broken white eyering that distinguishes it from similar flycatchers.
Its diet is opportunistic, consisting of a mix of small invertebrates gleaned from foliage and various small forest fruits.
Unlike many congeners, it is rarely found in upland terra firme forest, remaining strictly tied to riparian corridors.

Habitat

Seasonally flooded tropical forests (Várzea), river islands, and lakeside woodlands.

Range

The Amazon Basin of South America, including parts of Brazil, Peru, Ecuador, Colombia, Venezuela, and the Guianas.
