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

Recently reclassified from the genus Charadrius to Anarhynchus following extensive phylogenetic analysis.
The species was formally split from the Tibetan Sand-Plover (Anarhynchus atrifrons) based on distinct genetic and vocal differences.
Breeding occurs at high altitudes, often up to 5,500 meters, on sparsely vegetated mountain steppes and tundra.
Exhibits a distinctive 'run-stop-peck' foraging behavior typical of many plovers to capture small invertebrates.
Undergoes a significant molt into drab grey-brown non-breeding plumage, making field identification among other sand-plovers difficult.

Habitat

Breeds on stony alpine tundra and mountain ridges; winters on coastal mudflats, estuaries, and sandy beaches.

Range

Breeds in Northeastern Siberia and the Russian Far East; winters across Southeast Asia, Indonesia, and Australasia.
