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

The species was officially split from the Xantus's Murrelet complex in 2012 due to genetic and vocal distinctions.
Precocial chicks leave their island nest sites only two days after hatching to begin life on the open ocean.
Guadalupe Murrelets are among the most pelagic alcids, often venturing far beyond the continental shelf.
They utilize a wing-propelled diving technique to hunt small schooling fish and zooplankton at significant depths.
The primary breeding colony is restricted to Guadalupe Island, Mexico, where they face threats from invasive predators.

Habitat

Open pelagic waters and rocky, crevice-filled cliffs on offshore islands.

Range

Eastern Pacific Ocean, breeding primarily on Guadalupe Island and dispersing north to the California coast.
