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 uniquely identified among similar swallows by a prominent white supraloral streak that extends from the bill to above the eye.
The species is a secondary cavity nester, frequently utilizing old woodpecker holes, rock crevices, or human-made structures for breeding.
Southern populations are migratory, traveling north toward the Amazon basin and northern South America during the austral winter.
While foraging, they are often observed in pairs or small groups rather than the massive communal flocks typical of other swallow species.
Their plumage exhibits a deep blue-green gloss on the upperparts which contrasts sharply with their snowy white underparts and rump.

Habitat

Open or semi-open lowlands, including grasslands, pastures, and forest clearings, usually in close proximity to water.

Range

South-central South America, including northern Argentina, Uruguay, Paraguay, and southeastern Brazil.
