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

They construct elongated, pendulous nests made of woven fibers that can hang up to 60 centimeters long from tree branches.
The species is a prolific mimic, frequently incorporating the calls of other bird species and even monkeys into its own repertoire.
They exhibit significant sexual size dimorphism, with males being nearly twice as much as 60% larger than females.
Colonies are often strategically built near active wasp nests to deter potential arboreal predators like monkeys or snakes.
During courtship, males perform elaborate bowing displays while fanning their wings and raising their bright red rump feathers.

Habitat

Tropical lowland evergreen forests, forest edges, and seasonally flooded forests.

Range

South America, primarily the Amazon Basin, the Guianas, and the Atlantic Forest of Brazil, Paraguay, and Argentina.
