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.

Coscoroba Swan

Coscoroba coscoroba

The Coscoroba Swan is a unique South American waterfowl that represents an evolutionary link between true swans, geese, and whistling ducks. It is easily identified by its snowy white plumage, bright red bill, and bubblegum-pink legs.

What it sounds like

A loud, melodic, three-syllable trumpeting call that sounds like 'cos-cor-oo-ba,' from which its name is derived.

Field notes

Taxonomically, it is the only member of its genus and is more closely related to whistling ducks than to the 'true' swans in the genus Cygnus.
Unlike all other swan species, the Coscoroba Swan lacks a bare patch of skin (lores) between the eyes and the bill.
While the bird appears entirely white when swimming, the tips of its outer six primary feathers are jet black, a feature visible only during flight.
Coscoroba cygnets are distinctively patterned with bold black and white spots, resembling the ducklings of whistling ducks more than the greyish young of other swans.
It is the smallest bird to bear the name 'swan,' weighing significantly less than its northern hemisphere counterparts.

Habitat

Freshwater marshes, shallow lagoons, and lagoons with lush aquatic vegetation.

Range

Southern South America, primarily found in Chile, Argentina, Uruguay, and southern Brazil.
