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 rarest waterfowl, with an estimated wild population of fewer than 2,500 individuals.
Unlike most ducks, it is highly specialized for life in mangrove forests and brackish coastal wetlands.
The species nests exclusively in tree cavities, particularly within mature Avicennia mangrove stands.
They are primarily filter-feeders, using specialized bill lamellae to extract invertebrates and seeds from surface mud.
Bernier's Teal was once considered a subspecies of the Grey Teal but is now recognized as a distinct, isolated lineage.

Habitat

Mangrove swamps, shallow saline lagoons, and seasonal coastal wetlands.

Range

Endemic to the western and northern coasts of Madagascar.
