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

Frequently follows army ant swarms to capture insects and small invertebrates flushed by the ants.
It is the sole member of its genus, Euthlypis, making it evolutionarily distinct from other warblers.
The bird spends most of its time on the forest floor, walking rather than hopping while foraging.
Its plumage features a distinctive yellow crown patch and white 'spectacles' around the eyes.
Nests are domed structures built directly on the ground, often hidden under leaf litter or rock ledges.

Habitat

Dense undergrowth of tropical deciduous forests, gallery forests, and rocky ravines.
