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 morphologically distinguished from the Taiga Bean-Goose by its shorter, deeper bill and thicker neck.
The species name 'serrirostris' refers to the serrated edges of its bill, which it uses for grazing tough tundra vegetation.
They are strictly ground-nesters, typically placing their nests on elevated dry mounds to avoid wet tundra floors.
The orange coloration on the bill is highly variable between individuals, though generally more extensive than in the Taiga species.
The common name 'Bean-Goose' originates from their historical habit of foraging in bean field stubble during the winter months.

Habitat

Arctic tundra and shrublands during breeding; marshes, lakes, and agricultural fields during winter.

Range

Breeds across Northern Russia and Siberia; winters in East Asia and parts of Western Europe.
