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 closely related to the Red Warbler of central Mexico, sharing the genus Cardellina.
The species is classified as Vulnerable by the IUCN due to its small, fragmented range and ongoing deforestation.
Unlike many North American warblers, it is a non-migratory resident of high-elevation cloud forests.
Its unique pinkish-silver coloration is produced by specialized feather structures that reflect light differently than standard red pigments.
Nests are typically domed structures built on or near the ground, often tucked into banks or hidden by dense leaf litter.

Habitat

High-altitude humid pine-oak, cypress, and fir forests with dense undergrowth.

Range

Highlands of Chiapas, Mexico, and western Guatemala.
