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

The name 'Aplomado' is Spanish for 'lead-colored,' referring to the bird's distinctive blue-gray dorsal feathers.
They frequently hunt in mated pairs, where one bird flushes prey from cover while the other strikes from above.
Equipped with unusually long legs, these falcons are remarkably agile on the ground and can run down insects or small reptiles.
They do not build their own nests, instead utilizing abandoned stick nests constructed by other raptors or corvids.
Once nearly extirpated from the United States, dedicated reintroduction programs have established resident populations in South Texas and New Mexico.

Habitat

Open grasslands, tropical savannas, and shrub-steppes with scattered trees or yuccas.

Range

The Southwestern United States and Mexico through Central and South America to Tierra del Fuego.
