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 belonged to the Mohoidae family, the only avian family to become entirely extinct in the last several hundred years.
The species was characterized by its sooty black plumage, bright yellow axillary tufts, and long tail feathers tipped with white.
Recent DNA analysis confirms that despite its honeyeater-like appearance, it was more closely related to waxwings and silky-flycatchers.
The bird utilized a specialized brush-tipped tongue to feed on the nectar of native Hawaiian lobelioids and ohia lehua blossoms.
The last confirmed sightings and specimens date back to 1837, likely succumbing to habitat loss and avian malaria.

Habitat

Dense subtropical montane rainforests and high-elevation valleys.

Range

Endemic to the island of Oahu, Hawaii.
