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 one of the few bird species known to sing while actively incubating eggs on the nest.
Unlike many of its relatives, the Warbling Vireo lacks distinct field marks like wing bars or a bold eye-ring.
Eastern and Western populations have distinct vocalizations and subtle plumage differences, suggesting they may be separate species.
The nest is a sophisticated pensile cup made of spiderwebs and plant fibers, suspended from the fork of a high outer branch.
During the breeding season, its diet is almost entirely insectivorous, focusing heavily on caterpillars gleaned from foliage.

Habitat

Deciduous forests, riparian woodlands, and leafy suburban parks or orchards.

Range

Breeds across North America from southern Canada to northern Mexico; migrates to Central America for winter.
