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-chinned Petrel

Procellaria aequinoctialis

The White-chinned Petrel is a large, soot-colored seabird of the Southern Ocean, distinguished by its massive pale bill and variable white patch under the chin.

What it sounds like

A series of harsh, rattling croaks and wheezing staccato notes, typically heard only at breeding colonies or during competitive feeding.

Field notes

It is the heaviest member of the Procellariidae family that regularly dives, capable of reaching depths over 10 meters.
The species is one of the most frequent victims of longline fishing bycatch in the Southern Ocean due to its aggressive scavenging behavior.
Unlike many smaller petrels, it is a burrow-nester that can successfully defend its nesting site from smaller predators.
They employ a 'dual-foraging' strategy during the breeding season, alternating between short local trips and long-distance treks to productive frontal zones.
While predominantly dark, their bills are uniquely structured with pale horn-colored plates and a dark line between the nostrils.

Habitat

Pelagic open oceans and sub-Antarctic islands for breeding.

Range

Circumpolar distribution in the Southern Hemisphere, ranging from the Antarctic pack ice to subtropical waters.
