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 was formerly placed in the genus Thryothorus before being reassigned to Thryophilus based on molecular phylogenetics.
The species is visually distinguished from the similar Happy Wren by its colder brown upperparts and paler, less buffy underparts.
It constructs a distinctive retort-shaped nest with a side entrance, often suspended from a low-hanging branch in dense cover.
While primarily a Mexican endemic, it is a rare vagrant to the United States, with occasional records in southern Arizona.
It is highly territorial and frequently responds aggressively to recordings of its own complex song.

Habitat

Arid to semi-humid tropical deciduous forests, thorn scrub, and dense riparian undergrowth.

Range

Western Mexico, ranging from southeastern Sonora south to western Oaxaca.
