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

No confirmed sightings of the species have been recorded since June 1912, despite numerous targeted searches.
The species was unique among storm-petrels for its winter-spring breeding season, which avoided competition with summer-breeding relatives.
Introduction of feral cats to Guadalupe Island is cited as the primary driver of its rapid population collapse.
It nested exclusively in burrows located under the roots of Guadalupe cypress and pine trees at high elevations.
Morphologically, it was distinguished from the Leach's Storm-Petrel by its larger size and more deeply forked tail.

Habitat

Pelagic open ocean; high-altitude montane forests for nesting burrows.

Range

Guadalupe Island, Mexico, and the surrounding eastern Pacific Ocean.
