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 formally elevated to species status after being split from the Black-throated Trogon (Trogon rufus) based on distinct vocalizations and plumage.
The scientific name 'cupreicauda' literally translates to 'copper tail,' referring to the unique metallic sheen on the male's rectrices.
Like all trogons, it possesses heterodactyl feet, an arrangement where the first and second toes face backward and the third and fourth face forward.
They are known to be 'sit-and-wait' predators, remaining motionless for long periods before sallying out to pluck insects or fruit from foliage.
The species often nests in cavities excavated within active arboreal termite mounds, providing a stable microclimate and protection.

Habitat

Humid lowland and foothill evergreen forests, primarily in the shaded middle story.

Range

The Pacific slope of the Andes in western Colombia and northwestern Ecuador.
