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

Displays a 'spectacled' appearance created by white supercilium and malar stripes contrasting with rufous ear patches.
Commonly forages in low undergrowth or on the ground, often seen hopping with its long tail cocked upward.
Northern populations feature bright yellow underparts, while southern subspecies show significantly more white on the belly.
Remains in pairs or small family groups year-round rather than joining large migratory mixed-species flocks.
Primarily a resident of Mexico and Central America, it is a highly sought-after rarity in Southeast Arizona and South Texas.

Habitat

Dense brushy undergrowth, tropical deciduous forests, and oak-pine woodlands, often in rocky canyons.

Range

Mexico and Central America south to Colombia, with occasional sightings in the Southwestern United States.
