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.

Hutton's Vireo

Vireo huttoni

A small, inconspicuous songbird of western North America, often mistaken for a Ruby-crowned Kinglet due to its olive plumage and wing bars.

What it sounds like

A monotonous, repetitive 'zu-weep' or 'wee-tee' song with a rising or falling inflection.

Field notes

It is primarily non-migratory, remaining in its breeding territory year-round unlike most other vireo species.
Distinguishable from the Ruby-crowned Kinglet by its thicker, hooked bill and sturdier blue-gray legs.
The species is divided into two main groups: the Pacific coastal 'huttoni' group and the interior 'stephensi' group.
Nests are architectural hanging cups constructed from moss, lichen, and spider silk, typically suspended from a fork in a branch.
It exhibits a 'patient' foraging style, moving more slowly and deliberately through foliage than the hyperactive kinglets it mimics.

Habitat

Oak woodlands, mixed evergreen forests, and montane coniferous stands.

Range

Western North America from southwestern British Columbia to central Mexico, including parts of the Desert Southwest.
