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.

Laysan Duck

Field notes

It is the rarest native waterfowl in the United States and survived a population bottleneck of approximately 12 individuals in 1911.
The species exhibits a unique feeding behavior known as 'brine fly snapping,' where it runs through swarms of flies with its bill open.
While it is a capable flyer, it is largely sedentary and non-migratory, rarely venturing far from its natal island.
Historically found throughout the Hawaiian archipelago, subfossil records indicate it once lived alongside now-extinct flightless birds.
Translocation efforts since 2004 have successfully established new wild populations on Midway Atoll and Kure Atoll to mitigate the risk of extinction.

Habitat

Hypersaline lagoons, coastal scrubland, and freshwater seeps.

Range

Northwestern Hawaiian Islands (Laysan Island, Midway Atoll, and Kure Atoll).
