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.

Green-backed Tit

Parus monticolus

The Green-backed Tit is a colorful, small passerine bird closely resembling the Great Tit but distinguished by its vibrant moss-green mantle and yellow underparts divided by a bold black stripe.

What it sounds like

A varied and high-pitched series of whistles and chatter, often rendered as a rhythmic 'wi-chi-chi-chi' or a sharp 'tsee-tsee'.

Field notes

It is highly social and frequently participates in mixed-species foraging flocks to increase protection from predators.
The species is known for its altitudinal migration, descending from high-elevation forests to lower valleys during the winter months.
It is a secondary cavity nester, often lining tree hollows or abandoned woodpecker holes with moss, hair, and feathers.
Unlike the similar Great Tit, the Green-backed Tit features two distinct white wing-bars on its secondary coverts.
Their diet is omnivorous and opportunistic, consisting primarily of insects and larvae during the breeding season and seeds or berries in winter.

Habitat

Temperate and subtropical montane forests, including broadleaf, coniferous, and mixed woodlands, as well as rural gardens.

Range

The Himalayas, southern China, Taiwan, and parts of mainland Southeast Asia such as Vietnam and Myanmar.
