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.

What it sounds like

Thin, high-pitched 'tsee-tsee' contact notes and a soft, liquid, descending warbling song.

Field notes

The species was historically classified as a subspecies of Zosterops senegalensis before being elevated to full species status.
It possesses a specialized brush-tipped tongue used for efficiently extracting nectar from flowers.
Despite its small size, it is a key participant in mixed-species foraging flocks, often leading or following other insectivores.
The 'white eye' is actually a ring of tiny, specialized feathers rather than bare skin or a colored iris.
It exhibits distinct sexual monomorphism, meaning males and females are virtually identical in plumage and size.

Habitat

Moist savanna, gallery forests, woodland thickets, and forest edges.

Range

West-central Africa, primarily northern Angola, southern Democratic Republic of the Congo, and western Zambia.
