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

Juveniles possess distinct yellow bills and yellow eye-rings, which transition to solid black as they reach adulthood.
They are cooperative breeders, often living in large family groups where non-breeding individuals help raise the dominant pair's chicks.
The species is confined to a narrow endemic range along the Pacific slope of Mexico, specifically from Nayarit to Guerrero.
Unlike many other members of the genus Cyanocorax, the San Blas Jay lacks a prominent upright crest, having only short, stiff frontal feathers.
Their diet is highly opportunistic, ranging from insects and small lizards to fruit and the eggs of other bird species.

Habitat

Tropical deciduous forests, mangroves, coastal scrub, and shaded plantations.

Range

Western Mexico (Pacific coast).
