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

Displays pronounced sexual dimorphism: males possess brilliant yellow underparts and a black mask, while females are primarily olive-brown.
Commonly joins mixed-species foraging flocks, moving rapidly through the upper strata of the forest with other honeycreepers.
Feeds on a diverse diet of small fruits, berries, and nectar, occasionally gleaning insects from the underside of leaves.
Shows a strong ecological preference for riverine habitats, specifically varzea (flooded) forests and edges near water.
The species is often identified by its distinct bright yellow iris, which contrasts sharply against the dark plumage of the male's head.

Habitat

Lowland evergreen forest canopy, river edges, and seasonally flooded varzea forests.

Range

The Amazon Basin of South America, spanning across Brazil, Peru, Ecuador, Colombia, Bolivia, and southern Venezuela.
