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 displays the characteristic nuthatch ability to forage by climbing down tree trunks head-first.
The species often joins mixed-species foraging flocks alongside tits and warblers during the non-breeding season.
It is primarily sedentary, though some populations may undergo minor altitudinal movements in response to winter weather.
Nests are established in tree cavities, often with the entrance hole reduced in size using mud masonry to deter predators.
It closely resembles the Eurasian Nuthatch but is differentiated by its darker greyish-buff underparts and specific vent patterns.

Habitat

Montane evergreen and deciduous forests, frequently associated with oak, pine, and rhododendron stands.

Range

Eastern Himalayas, Northeast India, Myanmar, southern China, and parts of Indochina.
