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.

Tyrannus savana

A striking Neotropical kingbird easily recognized by its exceptionally long, deeply forked tail and contrasting black-and-gray plumage. It is an agile aerial insectivore known for its graceful flight and complex seasonal migrations.

What it sounds like

Dry, sharp 'tik' or 'zick' notes, often delivered in a rapid, staccato chattering sequence during flight.

Field notes

Adult males possess outer rectrices (tail feathers) that can reach up to three times the length of the bird's body.
The species is a noted austral migrant, with southern populations traveling north toward the Amazon basin and Caribbean during the Southern Hemisphere winter.
They possess a concealed yellow crown patch that is typically only flashed during territorial disputes or courtship displays.
During the non-breeding season, they become highly gregarious and can form communal roosts exceeding 10,000 individuals.
While primarily insectivorous, they switch to a heavily frugivorous diet during migration to satisfy high energy requirements.

Habitat

Open country including savannas, wet grasslands, pastures, and agricultural fields with scattered trees.

Range

Breeds from southern Mexico through Central America and South America to central Argentina.
