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.

Kelp Goose

Chloephaga hybrida

A specialized maritime waterfowl of southern South America, the Kelp Goose exhibits extreme sexual dimorphism and lives almost exclusively on rocky shorelines.

What it sounds like

Males produce a thin, high-pitched whistle; females give a harsh, repetitive cackling or quacking sound.

Field notes

Males are entirely snow-white with black bills and yellow legs, while females are dark brown with intricate white barring and pink feet.
Their diet is highly specialized, consisting almost exclusively of green algae (Ulva) and aquatic mosses scraped from rocks.
Unlike most other geese, they are strictly coastal and are rarely seen inland or on freshwater bodies.
They are typically seen in pairs or small family groups rather than the large, communal flocks common to other Chloephaga species.
Nests are often built on the ground near the high-tide mark, hidden among coastal grasses or kelp debris.

Habitat

Rocky coastlines, intertidal zones, and pebble beaches adjacent to kelp beds.

Range

Southern Chile, southern Argentina, Tierra del Fuego, and the Falkland Islands.
