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 the largest member of the Troglodytidae family, reaching lengths of up to 22 centimeters.
Unlike most other wrens, its wings and tail lack any dark barring, showing solid coloration instead.
The species is a cooperative breeder, with family groups working together to defend territory and raise young.
It builds large, conspicuous globular nests with side entrances, often situated in bull-horn acacia trees for protection.
Despite its name and size, it has one of the most restricted ranges of any Mexican bird, found only in a narrow Pacific strip.

Habitat

Tropical dry forest edges, coastal scrub, second-growth thickets, and shady agricultural plantations.

Range

Pacific slope of Chiapas, Mexico.
