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 previously classified as a subspecies of the Collared Bush-Robin but was recognized as a distinct species due to genetic and vocal differences.
The species exhibits sexual dimorphism, with males featuring slate-gray upperparts and females having olive-brown plumage.
Unlike many members of the Tarsiger genus, this species is a non-migratory resident of its island habitat.
It primarily forages in the dense forest understory, feeding on small insects and occasionally berries.
The male's striking white 'eyebrow' or supercilium is much more pronounced than in its closest mainland relatives.

Habitat

High-elevation coniferous and mixed broadleaf forests with dense shrub or bamboo undergrowth.

Range

Montane regions of Taiwan.
