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

Commonly called a 'whitestart' due to the conspicuous white outer tail feathers used to flush insect prey.
It is distinct among its genus for having a deep reddish-brown cap that contrasts with its slate-grey upperparts.
The species frequently participates in mixed-species foraging flocks to increase hunting efficiency and predator detection.
Its foraging technique involves drooping its wings and spreading its tail to startle insects into flight for easy capture.
It is primarily sedentary, inhabiting high-altitude montane forests throughout the year without long-distance migration.

Habitat

Humid montane forests, alder woodlands, and bushy forest edges.

Range

Eastern Andes of southern Bolivia and northwestern Argentina.
