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

Adults possess a characteristic white patch on the mantle, which is highly visible from above during flight.
It is a specialized predator of medium-sized birds and mammals, often employing high-speed, falcon-like stoops to capture prey.
Unlike many larger eagles, it is extremely maneuverable and capable of chasing agile prey through dense woodland or scrub.
Pairs are strongly territorial and typically remain together on their home range throughout the entire year.
Juvenile birds exhibit distinct cinnamon-rufous underparts, which transition to the streaked white adult plumage over four to five years.

Habitat

Rugged mountainous terrain, rocky cliffs, and open Mediterranean scrubland or dry woodland.

Range

Southern Europe, North Africa, the Middle East, and across South Asia to Southeast Asia.
