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 only two warbler species in North America to nest in cavities rather than open cups.
The species is named after Lucy Hunter Baird, the daughter of the first director of the United States National Museum.
They are highly specialized for desert life, often nesting in old woodpecker holes or under the peeling bark of mesquite trees.
During the breeding season, they can survive in temperatures exceeding 100°F by foraging in the shaded interior of dense canopies.
They are early migrants, often arriving at their breeding grounds in the Southwest as early as late February.

Habitat

Desert riparian corridors, particularly mesquite bosques and thickets of saltcedar or willow.

Range

Breeds in the Southwestern United States and Northwest Mexico; winters along the Pacific coast of Mexico.
