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 the highest-altitude wren species, frequently occurring at elevations up to 3,500 meters in the elfin forest zone.
The species primarily forages by probing moss, lichens, and bromeliads for small insects and spiders.
It constructs a globular, domed nest made of moss and rootlets, typically hidden in a mossy bank or tree trunk cavity.
Mountain Wrens often travel in pairs and are active participants in mixed-species foraging flocks alongside tanagers and warblers.
There are several recognized subspecies across its 4,000-mile range, showing subtle variations in plumage saturation and wing barring.

Habitat

Humid montane forests, cloud forests, and bamboo-rich elfin forests.

Range

The Andes mountain range from Venezuela through Colombia, Ecuador, Peru, and Bolivia to northwest Argentina.
