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.

Banggai Crow

Corvus unicolor

The Banggai Crow is a critically endangered corvid endemic to the Banggai Islands of Indonesia, famously rediscovered in 2007 after being feared extinct for over a century.

What it sounds like

A high-pitched, nasal, and rhythmic series of 'khwa-khwa-khwa' notes, lacking the deep resonance of larger crow species.

Field notes

The species was known only from two museum specimens collected in the 1880s until its rediscovery in the 21st century.
It is distinguished from the sympatric Slender-billed Crow by its significantly shorter tail and smaller body size.
The total population is estimated at fewer than 500 mature individuals, restricted to a very small area of occupancy.
Unlike many opportunistic crows, this species is highly sensitive to habitat disturbance and avoids human-altered landscapes.
Its iris is dark, which helps differentiate it from some other Indonesian corvids that possess pale irises.

Habitat

Primary montane and submontane evergreen forests, typically at elevations between 500 and 900 meters.

Range

Peleng Island in the Banggai Archipelago, Central Sulawesi, Indonesia.
