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

Features a thin white line extending from the base of the bill to just above the eye, known as a supraloral line.
Remains a year-round resident throughout its range, unlike many other migratory Tachycineta species.
Nests primarily in tree cavities or holes in man-made structures located over or very near water.
Feeds almost exclusively on small flying insects caught in low-level flight over water surfaces.
Exhibits highly territorial behavior during the breeding season, frequently chasing other swallows away from its nesting site.

Habitat

Mangrove swamps, coastal lagoons, estuaries, and slow-moving riverbanks.

Range

Coastal regions of Mexico and Central America, extending from the Yucatán Peninsula to Panama.
