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.

Chiloe Wigeon

Mareca sibilatrix

The Chiloe Wigeon is a distinctive South American dabbling duck characterized by its iridescent green head patch, barred flanks, and goose-like grazing behavior.

What it sounds like

A clear, musical three-note whistle, typically transcribed as 'whee-whee-low,' with the male producing the more melodic tones.

Field notes

Unlike most northern wigeons, the Chiloe Wigeon is nearly monomorphic, meaning males and females share very similar plumage.
The species is highly monogamous, and unlike many ducks, the male often stays to help protect the ducklings after they hatch.
The specific name 'sibilatrix' translates to 'whistler,' highlighting the bird's melodic and frequent vocalizations.
They are primarily terrestrial grazers, often found walking in meadows and fields to feed on grasses and clover rather than just aquatic vegetation.
They are strong fliers and are known to be partially migratory, moving to northern South America during the harsh austral winters.

Habitat

Freshwater lakes, marshes, lagoons, and surrounding damp grasslands or pampas.

Range

Southern South America, including Chile, Argentina, Uruguay, and the Falkland Islands.
