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 is named in honor of the prolific German-Cuban naturalist Juan Cristóbal Gundlach.
Four distinct subspecies are recognized, distributed across the main island and various offshore cays.
Unlike many North American vireos, this species is a non-migratory, year-round resident of the Cuban archipelago.
It frequently joins mixed-species foraging flocks, moving through dense undergrowth to find insects and small fruits.
The nest is a characteristic deep cup suspended from a thin horizontal fork in a low shrub or tree.

Habitat

Dense thickets, dry forests, mangroves, and scrubby woodlands.

Range

Endemic to Cuba, the Isla de la Juventud, and several offshore cays.
