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 one of the world's few flightless waterfowl, possessing significantly reduced wings and a lack of a keeled sternum.
The species is largely crepuscular or nocturnal to minimize the risk of predation by subantarctic skuas.
Pairs are highly territorial and occupy the same stretch of coastline or stream throughout the year.
Their diet is opportunistic and omnivorous, consisting of marine invertebrates, amphipods, and algae scavenged from kelp beds.
Population stability is currently maintained on predator-free outliers like Adams, Disappointment, and Enderby islands.

Habitat

Coastal shorelines, rock pools, kelp beds, and dense megaherb or tussock grasslands.

Range

Auckland Islands archipelago, south of New Zealand.
