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.

Stripe-breasted Starthroat

Heliomaster squamosus

The Stripe-breasted Starthroat is a large, distinctive hummingbird endemic to Brazil, recognized by its exceptionally long bill and a bold white stripe bisecting its underparts.

What it sounds like

A series of thin, high-pitched and sharp 'tsip' or 'seek' notes, occasionally repeated in a slow sequence.

Reference call, compare with what you heard

Field notes

It is the only member of the Heliomaster genus to feature a prominent white longitudinal stripe down the center of its breast and belly.
The male's gorget exhibits a brilliant iridescent violet-purple hue with a scaly texture that gives the species its scientific name 'squamosus'.
It possesses a long, nearly straight bill specifically adapted for extracting nectar from deep, tubular flowers.
Unlike many smaller hummingbirds, it frequently perches on high, exposed branches to hawk for flying insects mid-air.
The species displays sexual dimorphism, with females lacking the vivid purple throat and instead showing more muted, dusky-scaled throat plumage.

Habitat

Semi-open landscapes including forest edges, Cerrado, Caatinga, and suburban gardens.

Range

Endemic to eastern and central Brazil.
