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 was named in honor of William Edwin Brooks, a prominent 19th-century ornithologist who specialized in the birds of India.
The species is often confused with the Yellow-browed Warbler but is distinguished by its more uniform yellowish-green upperparts and lack of a dark bill tip.
It features a distinct, pale median crown stripe, which is a key diagnostic feature within the complex Phylloscopus genus.
The bird breeds at high altitudes, typically between 2,100 and 3,500 meters in subalpine coniferous zones.
During winter, it undergoes altitudinal migration, descending to the plains and foothills of the Indian subcontinent.

Habitat

Coniferous forests of juniper, fir, and cedar during breeding; gardens, orchards, and acacia scrub in winter.

Range

Breeds in northeastern Afghanistan, northern Pakistan, and northwest India; winters in the northern plains of India and Pakistan.
