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 a bamboo specialist, frequently associated with dense Chusquea thickets in montane regions.
Unlike most members of the genus Hemitriccus which are olive-green, this species is characterized by dull brown and cinnamon-buff tones.
It belongs to the 'tody-tyrant' group, identified by their broad, flat bills and habit of sitting upright and motionless.
The species captures prey via short, upward 'sally-strikes' to the undersides of leaves to snatch small invertebrates.
Its population is endemic to the high-altitude Atlantic Forest, making it a key indicator species for that specific biome's health.

Habitat

Understory of montane evergreen forests and bamboo thickets.

Range

Southeastern Brazil (Minas Gerais to Rio Grande do Sul) and northeastern Argentina (Misiones).
