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

Males deliver a continuous, complex song while hovering at altitudes of 50 to 100 meters, often for several minutes at a time.
The species possesses a short, rounded crest on the crown that can be raised or lowered depending on its level of excitement.
It is a ground-nesting specialist, constructing a grass-lined cup hidden within thick vegetation or cereal crops.
The Eurasian Skylark is highly migratory in the northern and eastern parts of its range, while southern populations are often sedentary.
Their diet shifts seasonally, focusing on insects and larvae during the breeding season and seeds or plant shoots in the winter.

Habitat

Open habitats including agricultural fields, grasslands, meadows, heaths, and coastal dunes.

Range

Native across Europe and temperate Asia; introduced to Australia, New Zealand, and parts of North America.
