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

The male possesses a prominent, reflective silver-white lower mandible that contrasts sharply with its blackish head.
The species exhibits strong sexual dimorphism; females are much duller, with brownish-red plumage and dark bills.
They are cooperative breeders where young from previous broods may help the parents raise new chicks.
Their diet is omnivorous, consisting of a wide variety of tropical fruits supplemented by insects gleaned from foliage.
Crimson-backed Tanagers are known to engage in 'mobbing' behavior, gathering in groups to harass potential predators like snakes.

Secondary forests, humid forest edges, clearings, and suburban gardens.

Range

Central and South America, primarily in Panama, Colombia, and Venezuela.
