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

Possesses a distinctive white wedge-shaped patch on the back that is highly visible during flight.
Unlike many other waders, it frequently preys on small fish, often chasing them through shallows.
The bill is notably recurved (upcurved), helping the bird to sweep for prey in soft substrate.
Highly migratory, with some populations traveling over 10,000 kilometers between northern breeding grounds and southern wintering sites.
Nests are typically placed on the ground in open bogs, often positioned next to a piece of wood or a stone to serve as a landmark.

Habitat

Coastal estuaries, saltmarshes, and mudflats during migration; breeds in taiga bogs and northern moorlands.

Range

Breeds across northern Eurasia; migrates to Africa, Southern Asia, and Australasia.
