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 feature a distinct white iris, whereas juveniles possess dark eyes and brown-mottled wing plumage.
Their population has significantly increased in urban areas due to their high adaptability as opportunistic scavengers of human refuse.
They are highly social and colonial nesters, often forming colonies of thousands on offshore islands.
The transition from the dark beak and legs of a juvenile to the bright red of an adult takes approximately two years.
Courtship rituals involve a specific 'long-call' posture and ritualized food begging or head-tossing behaviors.

Habitat

Coastal beaches, estuaries, rocky islands, and increasingly common in urban parks and landfills.

Range

Widespread across Australia, New Zealand, and New Caledonia.
