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

Commonly known as 'Amigo de hombre' (friend of man) because it frequently follows hikers to capture insects stirred up by their movement.
Employs a 'flush-pursuit' foraging technique, fanning its white outer tail feathers to startle prey into the air.
Builds a distinctive domed or 'roofed' nest with a side entrance, typically hidden on a sloping bank or among ground-level moss.
It is a regional endemic, restricted entirely to the high-altitude cordilleras of Costa Rica and western Panama.
The bright chestnut crown patch is a key diagnostic feature, which can be flared during territorial displays or when the bird is excited.

Habitat

Moist montane forests, cloud forest edges, and high-altitude bushy clearings or gardens.

Range

Highlands of Costa Rica and western Panama.
