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.

Birdsong field guide

Marsh Sandpiper

Tringa stagnatilis

A slender, elegant wader resembling a smaller and more delicate version of the Greenshank, characterized by its needle-like bill and very long legs.

What it sounds like

A sharp, thin, and repetitive 'teu-ee' or 'tyup', higher-pitched and less forceful than the Greenshank.

Field notes

Possesses a distinctive needle-thin, perfectly straight bill that lacks the upward curve of its larger relatives.
Displays a prominent white wedge-shaped patch extending from the tail up the back, highly visible during flight.
Known for its exceptionally long, yellowish-green legs that project significantly beyond the tail in flight.
Feeds with a characteristic energetic motion, often 'scything' its bill through shallow water to capture small invertebrates.
One of the most migratory Tringa species, traveling from Siberian breeding grounds to as far south as Australia and South Africa.

Habitat

Shallow freshwater or brackish wetlands, including marshes, lake margins, and flooded fields.

Range

Breeds in Eastern Europe and Central Asia; winters in Africa, Southern Asia, and Australasia.
