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

Unlike the ground-nesting Brown Noddy, this species constructs elevated nests in trees or shrubs using leaves and guano.
It primarily feeds by 'dipping' or surface-pattering to catch prey, rarely diving deep below the water's surface.
The Black Noddy is smaller and significantly darker than its close relatives, possessing a longer and more slender bill.
It is highly gregarious, often forming massive breeding colonies on oceanic islands that can include thousands of pairs.
The white forehead patch is used extensively in 'nodding' courtship displays to signal to potential mates.

Habitat

Tropical and subtropical oceanic islands, specifically utilizing woody vegetation like mangroves and Pisonia trees for nesting.

Range

Widespread throughout the tropical Pacific and Atlantic Oceans, including the Caribbean and northern Australian coasts.
