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

Possesses vibrant yellow supraloral spots and a matching yellow wash on the carpal joint of the wing.
Exhibits 'mouse-like' behavior, frequently running through dense vegetation rather than taking flight when disturbed.
Unlike many congeners, it thrives in humid tropical lowlands and disturbed agricultural clearings rather than arid zones.
Constructs well-concealed cup nests located on the ground or very low within thick grass tussocks.
The species is largely non-migratory, maintaining year-round territories throughout its extensive South American range.

Habitat

Humid grasslands, savannas, pastures, and grassy edges of rainforests.

Range

Widespread across South America east of the Andes, spanning from Colombia and Venezuela to northern Argentina.
