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.

Campbell Islands Teal

Anas nesiotis

The Campbell Islands Teal is a small, flightless, nocturnal dabbling duck endemic to New Zealand's subantarctic islands, once thought extinct until its rediscovery on a remote rock stack.

What it sounds like

Males produce thin, high-pitched wheezy whistles; females give soft, low-frequency quacks and 'pip-pip' contact calls.

Field notes

It is strictly flightless, an evolutionary adaptation resulting from the historical absence of terrestrial mammalian predators on its home islands.
The species was rediscovered in 1975 on the tiny, 23-hectare Dent Island after being eradicated from the main Campbell Island by introduced Norway rats.
Following the world's largest rat eradication program in 2001, the teal was successfully reintroduced to Campbell Island in 2004.
To avoid avian predators like the Brown Skua, the teal has adopted a predominantly nocturnal and crepuscular lifestyle, hiding in dense vegetation during the day.
Unlike many ducks, they are highly territorial and exhibit a cryptic, dark sepia plumage with a distinctive white eye-ring and green iridescence on the speculum.

Habitat

Dense tussock grasslands, megaherb fields, and rocky shorelines providing significant overhead cover.

Range

Campbell Island group, New Zealand Subantarctic.
