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 recently split into a distinct species from the Black-throated Trogon complex (Trogon rufus) based on vocal and genetic differences.
The species exhibits heterodactyl feet, a trait unique to trogons where the first and second toes point backward while the third and fourth point forward.
They often nest in active arboreal termite mounds, excavating a chamber where the termites' activity helps maintain a stable incubation temperature.
Males feature a shimmering metallic green back and a black throat, whereas females have a warm brown plumage in the same areas.
Foraging involves a technique called 'sally-gleaning,' where the bird hovers briefly to pluck fruit or insects from foliage before returning to a perch.

Habitat

Understory and mid-story levels of humid primary and mature secondary evergreen forests.

Range

Atlantic Forest of southeastern Brazil, eastern Paraguay, and northeastern Argentina.
