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

Formerly classified as a subspecies of the Three-striped Warbler (Basileuterus tristriatus) before being elevated to species status.
It is geographically isolated, found only on a few mountain peaks in the Serranía del Darién.
The species is characterized by a prominent buff-colored median crown stripe bordered by dark lateral stripes.
It typically forages in the lower to middle strata of the forest, often joining mixed-species flocks.
Despite its small range, it is currently classified as Least Concern, though its population remains poorly known due to habitat remoteness.

Habitat

Humid montane forests, mossy elfin forests, and dense undergrowth generally above 1,000 meters in elevation.

Range

The Darién Highlands of eastern Panama and adjacent northwestern Colombia.
