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 among the most widespread waterfowl in the world, natively inhabiting four different continents.
Unlike many duck species, both sexes exhibit identical plumage and share responsibilities in incubating eggs.
The species is largely nocturnal, frequently flying to flooded agricultural fields at night to forage for seeds.
They possess elongated toes that act like snowshoes, allowing them to traverse floating aquatic vegetation with ease.
Frequent 'egg-dumping' occurs, where females lay eggs in the nests of other ducks, including those of different species.

Habitat

Shallow freshwater marshes, flooded rice paddies, and seasonal wetlands with emergent vegetation.

Range

Pantropical distribution including the southern United States, South America, sub-Saharan Africa, and Southern Asia.
