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.

Atlantic Petrel

Pterodroma incerta

A large, robust gadfly petrel of the South Atlantic, identified by its distinctive dark brown hood and breast contrasting with a white belly.

What it sounds like

Silent at sea; at colonies, it emits high-pitched, whistled 'ti-ti-ti' notes and deeper, liquid 'ooh-wek' sounds.

Field notes

It breeds almost exclusively on Gough Island and the Tristan da Cunha archipelago.
The species is classified as Endangered, primarily due to heavy chick predation by invasive house mice on its main breeding grounds.
It is the only Pterodroma species where dark underwing coverts are paired with a clean white belly.
It performs a high-arching 'gadfly' flight, soaring in steep arcs even in low-wind conditions.
The Atlantic Petrel is largely nocturnal at its breeding colonies to minimize predation risks from Subantarctic Skuas.

Habitat

Open pelagic waters; breeds on temperate oceanic islands in burrows among ferns and tussock grass.

Range

South Atlantic Ocean, ranging from the subtropics to the edge of the Antarctic pack ice.
