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 one of the largest wren species in the world, reaching lengths of up to 22 centimeters.
Bicolored Wrens are cooperative breeders where adult offspring remain with their parents to help raise new broods.
They frequently build large, dome-shaped nests in thorny trees or close to wasp nests to deter potential predators.
The species is highly social and maintains territories through loud, synchronized duets performed by pairs and family groups.
Unlike most secretive wren species, they are bold and often forage openly on the ground for insects and small invertebrates.

Habitat

Arid to semi-arid scrublands, llanos, deciduous woodlands, and suburban gardens.

Range

Northern South America, including Colombia, Venezuela, Guyana, and northern Brazil.
