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

Despite its name, the Nashville Warbler only passes through Tennessee during migration and does not breed there.
The species name 'ruficapilla' refers to a small rufous crown patch that is typically concealed and rarely seen in the field.
It is a ground-nesting species, often concealing its nest in moss, leaf litter, or at the base of shrubs.
There are two distinct populations: an eastern subspecies and a western subspecies (formerly known as the Calaveras Warbler).
Alexander Wilson, the 'Father of American Ornithology,' named the bird after collecting a specimen in Nashville in 1811.

Habitat

Boreal bogs, open deciduous or mixed woods, and shrubby successional habitats.

Range

Breeds in the northern U.S., southern Canada, and western mountains; winters primarily in Mexico.
