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.

Upland Sandpiper

Bartramia longicauda

The Upland Sandpiper is a unique, terrestrial shorebird of the grasslands, characterized by its long neck, small head, and large, dark eyes. Unlike most sandpipers, it avoids coastal areas, preferring the open interior prairies of the Americas.

What it sounds like

A distinctive, ethereal, and mournful 'wolf-whistle' that rises in pitch and then slowly fades away.

Field notes

It is the sole member of the monotypic genus Bartramia, making it taxonomically distinct from other sandpipers.
Upon landing on a perch, it habitually holds its wings raised high above its back for several seconds before folding them.
Despite being a shorebird, it is almost never found near water, instead spending its life in dry meadows and hayfields.
The species is a long-distance migrant, traveling over 6,000 miles from North American breeding grounds to the South American Pampas.
They are known as 'fence-post birds' due to their habit of using posts and poles as lookout points to survey for predators and insects.

Habitat

Native tallgrass and shortgrass prairies, hayfields, pastures, and occasionally airport grasslands.

Range

Breeds across central and northern North America; winters in the pampas of Argentina, Uruguay, and southern Brazil.
