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 strictly endemic to the Altiplano Cundiboyacense in the Eastern Cordillera of Colombia.
The species is classified as Endangered, primarily due to habitat fragmentation and the drainage of high-altitude wetlands.
Unlike many lowland rails, it lives at elevations typically ranging from 2,500 to 4,000 meters above sea level.
Its plumage features a distinctive contrast between slate-grey underparts and olive-brown, black-streaked upperparts.
The bird is highly secretive, often staying within dense stands of Typha and Scirpus reeds to avoid predators.

Habitat

Temperate freshwater marshes and reed beds dominated by bulrushes and cattails.

Range

Eastern Andes of Colombia (Cundinamarca and Boyacá).
