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 Father Armand David, a French missionary and naturalist who first described many species in East Asia.
Formerly considered a subspecies of the Spotted Bush Warbler, it was elevated to species status based on distinct vocalizations and DNA.
The species is notoriously 'mouse-like' in behavior, preferring to run through thick grass rather than fly when disturbed.
It features subtle, dark spotting on the breast which is often less pronounced than in its close relative, the Spotted Bush Warbler.
The bird undergoes long-distance migration, breeding in the temperate forests of Siberia and wintering in the tropical regions of Southeast Asia.

Habitat

Montane scrub, dense forest understory, and tall grass thickets near water or forest edges.

Range

Breeds in Southeast Siberia, Mongolia, and Northern China; winters in Thailand, Laos, and Vietnam.
