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

The middle toe can reach up to 23mm in length, nearly equalling the length of the tarsus.
It is often described as a miniature version of the Wood Sandpiper due to its upright posture and structural proportions.
Unlike many related stints, it prefers inland freshwater wetlands and marshy vegetation over open coastal mudflats.
Its long toes are an evolutionary adaptation for walking across soft, floating mats of vegetation without sinking.
In breeding plumage, it shows a distinctive bright rufous crown and strongly patterned mantle feathers.

Habitat

Peat bogs, wet tundras, flooded fields, and freshwater marsh margins.

Range

Breeds in Siberia; migrates to South and Southeast Asia and Australasia.
