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

Its golden-yellow feathers were the primary source for the 'ahu 'ula (feather cloaks) and mahiole (helmets) worn by Hawaiian high royalty.
The bird possessed an exceptionally long, decurved bill specifically evolved for reaching nectar in deep, tubular lobelioid flowers.
It was one of the largest honeycreepers, measuring approximately 9 inches in length with a predominantly glossy black body.
The species was last sighted in 1898, with extinction likely caused by a combination of habitat loss, avian malaria, and over-harvesting.
Historical accounts suggest the bird was quite shy and spent most of its time in the high canopy of native forests.

Habitat

High-elevation montane rainforests, particularly those rich in 'ōhi'a lehua and endemic lobeliads.

Range

Endemic to the island of Hawaii (Big Island).
