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.

Frequently joins mixed-species foraging flocks, actively gleaning insects from the undersides of leaves in the canopy.
Constructs a domed nest made of moss and fibers, usually tucked into a mossy bank or low vegetation.
Exhibits altitudinal migration, breeding in high-elevation forests and descending to lower foothills during winter.
Belongs to a complex of morphologically similar species that are often best identified by their specific vocalizations.

The Himalayas and southern China through Myanmar, Thailand, and Indochina.
