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

It is the most widespread member of the genus Pseudobulweria, which contains some of the world's rarest seabirds.
The species exhibits a distinctively 'bull-necked' appearance in flight due to its robust neck and massive bill structure.
Nests are located in burrows or rock crevices on high-elevation volcanic ridges, sometimes exceeding 2,000 meters in altitude.
Unlike many other gadfly petrels, it is frequently observed foraging during the day, though it remains strictly nocturnal at breeding colonies.
The Tahiti Petrel is capable of diving several meters underwater to pursue prey such as squid and small fish.

Habitat

Pelagic environments in tropical waters; nests on rugged, forested mountain slopes and volcanic cliffs.

Range

Tropical and subtropical Pacific Ocean, ranging from the Solomon Islands and New Caledonia to French Polynesia.
