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 the largest member of its genus, Arremonops, measuring up to 16.5 centimeters in length.
Unlike many open-nesting sparrows, it builds a bulky, domed structure with a side entrance near the ground.
Juveniles are notably different from adults, lacking the distinct head stripes and possessing yellowish, streaked plumage.
The species is primarily terrestrial, using its stout bill to forage for insects and seeds in leaf litter.
While mostly skulking in dense cover, males frequently sing from elevated, exposed perches during the breeding season.

Habitat

Humid lowland forest edges, dense second-growth thickets, and shrubby agricultural borders.

Range

Central and South America, ranging from eastern Honduras to northern Peru and western Brazil.
