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.

Copper-tailed Hummingbird

Saucerottia cupreicauda

A medium-sized hummingbird endemic to the Guiana Highlands, best identified by its vibrant green plumage and contrasting metallic copper-bronze tail. It is a characteristic species of the rugged tepui slopes where it aggressively defends nectar sources.

What it sounds like

A high-pitched, thin series of squeaky 'tsip' or 'tseee' notes, occasionally delivered in a rapid, descending trill.

Field notes

It was formerly treated as a subspecies of the Steely-vented Hummingbird but is now recognized as a distinct species within the Saucerottia genus.
The species is restricted to the Pantepui biogeographic region, inhabiting the isolated table-top mountains of the Guiana Shield.
Its plumage features a glittering green crown and breast that transitions into a bronzy-green rump and a deep coppery-red tail.
While primarily a nectarivore, it frequently engages in 'hawking' to capture small flying insects for protein.
The population is divided into several subspecies, such as S. c. duidae and S. c. laireti, varying slightly in plumage saturation across different tepuis.

Habitat

Humid montane forest edges, shrubby slopes, and secondary growth near tepui massifs.

Range

Southern Venezuela, western Guyana, and extreme northern Brazil.
