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.

White-rumped Sandpiper

Calidris fuscicollis

The White-rumped Sandpiper is a long-distance migratory shorebird distinguished by its exceptionally long wings and a hidden white patch on the upper tail coverts. It is a member of the 'peep' group but is easily identified in flight by its namesake field mark.

What it sounds like

A very thin, high-pitched, mouse-like squeak, often transcribed as a sharp 'jeet' or 'tzit'.

Field notes

It performs one of the longest migrations in the Western Hemisphere, traveling over 8,000 miles from the High Arctic to southern South America.
Unlike most other small sandpipers, its wings are so long that they extend significantly beyond the tip of the tail when folded.
The white rump patch is actually formed by the upper-tail coverts and is typically only visible when the bird is in flight.
During the breeding season, males perform unique hovering flight displays while producing rhythmic, guttural, and metallic sounds.
They are primarily 'head-up' feeders, often wading into deeper water than other peeps to probe for aquatic invertebrates and larvae.

Habitat

Breeds on wet Arctic tundra; utilizes mudflats, freshwater marshes, and coastal estuaries during migration and winter.

Range

Breeds across the High Arctic of North America; migrates through central/eastern North America to winter in southern South America, including Tierra del Fuego.
