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.

White-faced Storm-Petrel

Pelagodroma marina

What it sounds like

Field notes

Commonly referred to as the 'Frigate Petrel' due to its long legs and erratic, dancing flight style.
Utilizes a characteristic 'skipping' motion, pushing off the water's surface with its feet to stay aloft while feeding.
Strictly nocturnal at breeding colonies to minimize the risk of predation by larger gulls and skuas.
Nests in long, winding burrows excavated in soft soil or beneath dense vegetation on remote, predator-free islands.
Possesses a highly developed sense of smell used to locate concentrated patches of plankton and find its specific burrow in total darkness.

Habitat

Pelagic open waters; breeds on remote offshore islands and rocky islets.

Range

Widespread across the Atlantic, Indian, and South Pacific Oceans, ranging from subtropical to subantarctic waters.
