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.

Birdsong field guide

Mexican Duck

Anas diazi

A large dabbling duck closely resembling a dark female Mallard, where both sexes lack the iconic iridescent green head of their relatives.

What it sounds like

A series of Mallard-like quacks; females give a loud, descending series, while males produce a softer, raspy 'rab-rab'.

Field notes

Formerly classified as a subspecies of the Mallard, it is now recognized as a distinct species due to genetic and plumage differences.
Unlike Mallards, males and females exhibit similar mottled brown plumage, though males typically have brighter yellow bills.
The species frequently hybridizes with Mallards in the northern parts of its range, complicating conservation of pure genetic lineages.
It is primarily non-migratory, staying within its breeding range year-round unless local water sources dry up.
Both sexes possess an iridescent blue-green speculum on the wing, bordered by thin white or black bars.

Habitat

Freshwater marshes, shallow lakes, flooded fields, and high-altitude wetlands.

Range

Southwestern United States (Arizona, New Mexico, Texas) through central Mexico.
