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

Mates for life, often remaining with the same partner for over 20 years in the wild.
Undergoes a complete synchronous molt after the nesting season, rendering the birds flightless for approximately 20 to 40 days.
Goslings are precocial and are capable of swimming and diving immediately after hatching.
V-formation flight allows the flock to increase its flying range by approximately 71% compared to a bird flying alone.
Urbanization has led to a significant increase in non-migratory 'resident' populations that remain in one area year-round.

Habitat

Lakes, ponds, bays, marshes, and human-modified landscapes such as golf courses and city parks.

Range

Native to North America; widely introduced to Europe, New Zealand, and parts of South America.
