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 few members of the Phylloscopidae family that is entirely non-migratory and sedentary.
The species is divided into two subspecies: the nominate on Bioko and P. h. camerunensis on the mainland.
It frequently participates in mixed-species foraging flocks, often associating with white-eyes and other montane insectivores.
The nest is a characteristic globular ball of moss, lichen, and fine fibers, usually tucked into an epiphyte or tree fork.
Its foraging behavior is highly energetic, involving constant wing-flicking while gleaning insects from the underside of leaves.

Habitat

Primary montane evergreen forests and well-developed secondary growth, typically above 1,000 meters elevation.

Range

The Cameroon Highlands of eastern Nigeria and western Cameroon, and the island of Bioko.
