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 classic austral migrant, breeding in the south and flying as far north as the Amazon basin during the winter months.
It is closely related to the White-rumped Swallow but can be distinguished by its lack of white feathers between the eye and the bill (lores).
Nesting typically occurs in natural cavities like rock crevices or tree holes, though it readily adapts to man-made eaves and nest boxes.
The species displays a high degree of site fidelity, with individuals often returning to the exact same nesting location in successive years.
During the non-breeding season, they form large communal roosts, sometimes numbering in the thousands, frequently gathering in reedbeds.

Habitat

Open fields, grasslands, and marshes, usually in close proximity to water sources.

Range

Breeds in Chile and Argentina; migrates north to Bolivia, Paraguay, and Brazil during the austral winter.
