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 nearly identical to the Wandering Tattler but can be distinguished by its shorter nasal groove and distinct two-syllable flight call.
During the breeding season, it develops fine horizontal gray barring across its breast and flanks.
It is known for 'teetering,' a constant upward and downward bobbing of the tail and hindquarters while foraging.
Unlike many other sandpipers, it frequently perches on solid objects such as rocks, mangrove roots, and even jetties.
The species performs incredible non-stop migratory flights between its Siberian breeding grounds and Australasian wintering sites.

Habitat

Rocky coasts, coral reefs, mangroves, and mudflats; breeds along stony riverbeds in subarctic tundra.

Range

Breeds in Northeast Siberia; winters in Southeast Asia, Australia, and New Zealand.
