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.

Reunion Fody

Foudia delloni

An extinct species of weaver endemic to Réunion, known only from 17th-century historical accounts and subfossil remains. It was significantly larger and more robust than the Red Fody that currently inhabits the island.

What it sounds like

Historical accounts suggest a chirping similar to other weaver birds, though specific details were never recorded.

Field notes

The species is known to science primarily through a 1674 description by the traveler Sieur Dubois.
Breeding males possessed a brilliant red head, neck, and breast, while the wings and tail remained brownish.
It vanished rapidly following the introduction of black rats to the island, likely becoming extinct by the 1680s.
No skins or taxidermy specimens of this bird exist in any museum worldwide; knowledge is based on traveler logs and bones.
It was once thought to be a variation of the Madagascar Fody before being taxonomically recognized as a distinct, larger species.
