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 most geographically restricted bird species in Central America, confined to just a few isolated mountain peaks.
The species is characterized by a distinctive chestnut-colored crown bordered by thin black stripes and a pale yellow eyebrow.
It primarily inhabits stunted elfin forests and dense montane thickets, typically found at elevations above 1,200 meters.
Formerly considered a subspecies of the Golden-crowned Warbler, it was elevated to a full species based on distinct plumage and vocalizations.
Due to its extremely small range and specialized habitat requirements, it is currently classified as Vulnerable by the IUCN.

Habitat

Montane cloud forest, elfin forest, and humid shrubby borders.

Range

Highlands of the Darién region (specifically Cerro Pirre and Serranía de Jungurudó) in eastern Panama and adjacent northwest Colombia.
