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 thrives at extreme elevations, often found between 3,500 and 4,800 meters in the Altiplano.
Unlike many other yellow-finches, it lacks yellow on the wings, featuring grayish-brown wing coverts instead.
It is a highly social species, frequently forming mixed-species flocks with other seed-eaters like Sierra-Finches.
It often utilizes man-made structures, such as stone walls and eaves, for nesting sites in addition to natural rock fissures.
The species is named for its citron-yellow lower back and rump, which provide a sharp contrast to its grayish mantle during flight.

Habitat

High-elevation Puna grasslands, rocky slopes, and the vicinity of Andean villages.

Range

Central and southern Andes, spanning Peru, Bolivia, northern Chile, and northwest Argentina.
