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 was formerly known as the Magnificent Hummingbird before being split into two distinct species in 2017.
Among the largest hummingbirds in the United States, it can reach a length of up to 5.5 inches.
Unlike smaller hummingbirds that flap constantly, Rivoli's often incorporates brief glides while traveling between nectar sources.
To survive cold mountain nights, it can enter a state of torpor, drastically lowering its body temperature and metabolic rate.
The species exhibits strong sexual dimorphism; females lack the iridescent crown and throat, featuring a greyish underside and a white spot behind the eye.

Habitat

High-altitude pine-oak forests, montane canyons, and humid mountain woodlands.

Range

Southwestern United States (primarily Arizona and New Mexico) through Mexico to Nicaragua.
