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

It is globally restricted to a very small range within the states of Tamaulipas, Veracruz, and San Luis Potosí.
Males are distinguished from the Common Yellowthroat by the bright yellow (rather than white) border above their black mask.
The species is currently classified as Vulnerable due to the fragmentation and drainage of its specialized wetland habitats.
It is a non-migratory species, remaining in its restricted freshwater marsh range year-round.
Foraging occurs almost exclusively low in dense emergent vegetation where it gleans insects and small invertebrates.

Habitat

Freshwater marshes and lagoons dominated by cattails (Typha) and bulrushes.

Range

Atlantic slope of northeastern Mexico.
