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 'Bundok' is derived from the Tagalog word for 'mountain', referring to its restricted high-altitude range.
It exhibits significant sexual dimorphism, with males featuring blue-grey upperparts and females possessing olive-brown plumage.
Taxonomic separation from Ficedula hyperythra was primarily driven by distinct differences in vocalizations and mitochondrial DNA.
The male is easily identified by its short, white 'eyebrow' or supercilium and a bright rufous throat and breast.
It is a shy, understory-dwelling species that primarily feeds on small insects caught in short aerial sallies.

Habitat

Primary montane and mossy forests, typically found at elevations above 1,000 meters.

Range

Endemic to the Philippines, specifically on the islands of Luzon, Mindoro, Panay, Negros, and Mindanao.
