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 currently classified as Vulnerable by the IUCN due to rapid habitat loss and its highly restricted geographic range.
Unlike most other wood-rails, it lacks rufous or chestnut tones on its head and neck, presenting a more uniform, duller coloration.
The species is largely terrestrial and prefers to escape threats by running into dense undergrowth rather than flying.
It is a flagship species for the Chocó-Darién moist forests, one of the most biodiverse but threatened regions on Earth.
Pairs are known to be highly territorial, frequently engaging in loud, synchronized vocal displays during dawn and dusk.

Habitat

Mangrove forests, freshwater swamps, and seasonally flooded lowland evergreen forests.

Range

Humid lowlands of western Colombia, western Ecuador, and extreme northwestern Peru.
