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

Displays extreme sexual dimorphism: males are bright blue above and chestnut below, while females are entirely brown and grey with intricate scaly patterns.
Unlike many members of its genus that prefer barren rock, this species is frequently found in pine forests and open temperate woodlands.
It is an altitudinal migrant, breeding at elevations up to 3,500 meters and descending to lower foothills during the winter months.
The species often adopts a 'sit-and-wait' hunting strategy, diving from a high perch to catch insects or small lizards on the ground.
During the breeding season, it is highly territorial and typically nests in rocky crevices or holes in steep earthen embankments.

Habitat

Open montane forests, pine-oak woodlands, and steep rocky hillsides.

Range

The Himalayas (India, Nepal, Bhutan) through southern China and northern Southeast Asia.
