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 belongs to Prunellidae, the only bird family entirely endemic to the Palearctic region.
Unlike the widespread Dunnock, this species features deep rufous-brown tones on its flanks and breast.
It is a specialized breeder of the 'creeping pine' (Pinus pumila) zone found above the alpine timberline.
The species is an altitudinal migrant, moving from mountain peaks to lowland thickets and gardens during winter.
Despite its small size, it is hardy and often remains in snowy areas as long as dense cover is available.

Habitat

Alpine scrub, dwarf pine thickets, and montane coniferous forests; lowland brush in winter.

Range

Endemic to Japan (Hokkaido, Honshu, Kyushu) and Sakhalin Island, Russia.
