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 relies on highly effective disruptive coloration to remain nearly invisible while roosting on the forest floor during the day.
The species is frequently located at night by its distinct orange eyeshine when reflecting artificial light.
Unlike many birds, it constructs no nest, laying two creamy, blotched eggs directly onto the leaf litter.
It possesses specialized rictal bristles around the gape that assist in the tactile detection and capture of flying insects.
Taxonomically, it is divided into two subspecies: one on the mainland of Cuba and a smaller variant on Isla de la Juventud.

Habitat

Dense lowland forests, semi-deciduous woodlands, and the edges of mangrove swamps.

Range

Endemic to the Republic of Cuba and Isla de la Juventud.
