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

Belongs to the 'sheartail' group, characterized by the male's elongated and deeply forked tail feathers.
Unlike the closely related Lucifer Hummingbird, this species is largely non-migratory within its restricted range.
Males possess elongated gorget feathers that can be flared laterally during competitive or courtship displays.
The bill is distinctly decurved, an evolutionary adaptation for foraging on the tubular flowers of cacti and agaves.
Females lack the iridescent throat and exhibit a warm cinnamon-buff wash across their underparts and flanks.

Habitat

Arid to semi-arid scrubland, thorn forests, and cactus-dominated landscapes.

Range

South-central Mexico, primarily within the states of Puebla, Oaxaca, and Guerrero.
