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.

Nordmann's Greenshank

Tringa guttifer

A critically endangered shorebird of the East Asian-Australasian Flyway, distinguished from the Common Greenshank by its stouter, bicolored bill and shorter, yellowish legs.

What it sounds like

A loud, piercing, and resonant 'kyuu-kyuu' or 'gwa-gwa', typically deeper and more abrupt than the call of the Common Greenshank.

Field notes

It is one of the rarest waders in the world, with a global population estimated at only 600 to 1,300 individuals.
Uniquely among its genus, it is known to nest in trees, specifically building nests on the branches of larch trees in the Russian Far East.
The species possesses distinctive partial webbing between all three front toes, a feature more pronounced than in other Tringa species.
During the breeding season, it displays heavy, drop-shaped black spotting on its neck and breast, which is reflected in its specific name 'guttifer'.
It is highly dependent on a few key stopover sites in the Yellow Sea to complete its long-distance migration between Russia and Southeast Asia.

Habitat

Coastal mudflats, estuaries, and saltpans during migration and winter; larch-dominated taiga and coastal meadows for breeding.

Range

Breeds in eastern Russia (Sakhalin and Sea of Okhotsk); winters in Southeast Asia, including Thailand, Malaysia, and Vietnam.
