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 is the only member of the genus Psittirostra, representing a distinct evolutionary lineage among Hawaiian honeycreepers.
The species displays striking sexual dimorphism, with males featuring a brilliant yellow head while females are almost entirely olive-green.
Unlike most honeycreepers, the 'O'u was a nomadic flyer, traveling long distances between different elevations to follow seasonal fruiting cycles.
Its unique, hooked bill is an evolutionary adaptation specifically designed to pry apart the dense bracts of 'ie'ie fruits.
The last confirmed sightings occurred in the late 1980s following catastrophic habitat loss from Hurricane Iwa and the 1984 eruption of Mauna Loa.

Habitat

High-elevation montane wet forests, specifically those with a dense understory of 'ie'ie vines (Freycinetia arborea).

Range

Endemic to the Hawaiian Islands; historically found on all main islands but last restricted to Kauai and Hawaii Island.
