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

Closely resembles a giant version of the Common Black Hawk but possesses much broader, paddle-shaped wings.
Primarily a specialist predator of snakes, although it also takes small mammals and birds.
Its tail is notably short, typically showing a single prominent white median band and a narrow white tip.
Listed as Near Threatened, it occurs at very low densities and requires large tracts of undisturbed forest to survive.
The species was formerly placed in its own genus, Harpyhaliaetus, before molecular data moved it to Buteogallus.

Habitat

Primary montane and foothill forests, generally between 600 and 2,200 meters in elevation.

Range

Fragmented range from Mexico through Central America to the Andean slopes of South America.
