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

They possess heterodactyl feet, a trait unique to trogons where the first and second toes point backward while the third and fourth point forward.
Both sexes frequently collaborate to excavate nesting cavities within active arboreal termite mounds.
Their diet is omnivorous, consisting of insects snatched from foliage and small fruits consumed while hovering momentarily.
The species exhibits strong sexual dimorphism; males have a brilliant blue-violet crown and green back, whereas females are primarily grey.
They are often observed sitting motionless for long periods, making them difficult to spot despite their bright colors.

Habitat

Humid lowland forests, gallery forests, and secondary growth woodlands.

Range

Widespread across central and southern South America, including the Amazon Basin, Brazil, Paraguay, and northern Argentina.
