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 performs a signature 'double-tap' drum, a rapid-fire two-stroke sequence characteristic of the Ivory-billed Woodpecker lineage.
Unlike most of its close relatives, it lacks white stripes or a 'V' pattern on its back, appearing solid black from behind.
It is one of the largest woodpecker species in South America, reaching lengths of up to 35 centimeters.
Its diet is highly specialized, focusing on large wood-boring beetle larvae extracted from deep within decaying hardwood.
The species shows subtle sexual dimorphism where the male possesses a red malar stripe that is absent in the female.

Habitat

Humid montane forests and foothill evergreen forests, typically at elevations between 800 and 2,500 meters.

Range

The Andes of Colombia, Ecuador, and Peru.
