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 primarily crepuscular, specifically hunting bats, swifts, and large insects at dawn and dusk.
The plumage features a blackish head and back contrasting with a white throat and finely barred black-and-white breast.
It exhibits pronounced reverse sexual dimorphism, with females weighing up to twice as much as males.
Pairs often hunt together, with one bird flushing prey while the other intercepts it mid-air.
It typically perches on high, exposed dead branches or 'snags' to maintain a clear line of sight over forest clearings.

Habitat

Tropical forest edges, clearings, and gallery forests, often near water or archaeological sites.

Range

From southern Mexico through Central America to northern Argentina and Paraguay.
