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.

Beck's Petrel

Pseudobulweria becki

Beck's Petrel is a rare, small gadfly petrel that was considered extinct for nearly 80 years before its rediscovery in 2007. It remains one of the world's most enigmatic and critically endangered seabirds.

What it sounds like

Largely unknown; likely silent at sea, while potentially using whistles or croaks near suspected inland nesting sites.

Field notes

The species was known only from two specimens collected in the 1920s until it was rediscovered in the Bismarck Sea by Hadoram Shirihai.
It is morphologically similar to the Tahiti Petrel but is significantly smaller with a shorter wingspan and a more slender bill.
Despite recent sightings at sea, its official nesting grounds have never been found by scientists.
Current population estimates are extremely low, often cited as fewer than 250 mature individuals remaining in the wild.
It belongs to the genus Pseudobulweria, a group of 'primitive' petrels that are often highly localized and prone to extinction.

Habitat

Pelagic open ocean; suspected to breed in high-altitude, remote montane forests.

Range

Western Pacific Ocean, specifically around the Bismarck Archipelago and Solomon Islands.
