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.

Chestnut-bellied Nuthatch

Sitta cinnamoventris

A robust and active member of the Sitta genus, the Chestnut-bellied Nuthatch is distinguished by its striking rufous underparts and its remarkable ability to navigate tree trunks with agility.

What it sounds like

A rapid, high-pitched series of 'sit-sit-sit-sit' notes or a loud, nasal 'quirp' often repeated in quick succession.

Field notes

It was historically considered conspecific with the Indian Nuthatch and Burmese Nuthatch until taxonomic splits recognized them as distinct species.
The species displays significant sexual dimorphism; males have deep, dark chestnut underparts, while females are noticeably paler.
Like other nuthatches, it can move down tree trunks head-first, a feat made possible by its exceptionally strong hind toes and claws.
It often participates in mixed-species foraging flocks, moving quickly through the canopy alongside warblers and titmice.
The bird frequently utilizes 'caching' behavior, wedging seeds or insects into bark crevices to store them for later consumption.

Habitat

Subtropical and tropical moist montane forests, particularly those featuring oak, pine, and rhododendron trees.

Range

The Himalayan foothills across Pakistan, India, Nepal, and Bhutan, extending into parts of Southeast Asia including Myanmar and Vietnam.
