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.

Pine Warbler

Setophaga pinus

Field notes

It is one of the few warbler species that regularly eats seeds, specifically from various pine species.
Unlike most migratory warblers, it remains in the southeastern United States throughout the winter.
It is almost never found outside of pine stands, making it one of the most habitat-specific warblers.
Pine Warblers are often the first warblers to begin singing in the early spring, sometimes as early as February.
They creep along thick branches and pine cones rather than flitting rapidly through foliage like other Setophaga species.

Habitat

Open pine forests, barrens, and mixed pine-hardwood stands.

Range

Eastern North America, from southern Canada to the Gulf Coast and parts of the Caribbean.
