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

Despite its finch-like conical bill, genetic analysis places this species in the tanager family (Thraupidae).
They construct globose, domed nests with a side entrance, often hidden low in dense grass or shrubs.
Males perform a distinct courtship display where they vibrate their wings rapidly while perched near a female.
The species is highly gregarious and often forages in small flocks alongside other seedeaters and grassquits.
While primarily granivorous, they are known to supplement their seed-based diet with small insects and nectar.

Habitat

Open grasslands, pastures, agricultural fields, and brushy roadsides.

Range

Greater Antilles, Mexico, Central America, and northwestern South America.
