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.

Golden-winged Warbler

Vermivora chrysoptera

A striking New World warbler identified by its silvery-gray plumage, bold yellow wing bars, and contrasting black throat and eye mask. It is a species of high conservation concern due to habitat loss and hybridization.

What it sounds like

A high, buzzy song consisting of one primary note followed by several lower ones: 'zee-bee-bee-bee'.

Field notes

Frequently hybridizes with the Blue-winged Warbler, producing distinct fertile hybrids known as 'Brewster’s' and 'Lawrence’s' warblers.
Has one of the steepest population declines of any North American songbird, particularly in the Appalachian Mountains.
Nests are typically constructed on the ground, often hidden at the base of leafy herbaceous plants like goldenrod.
Breeding success often depends on 'feathered edges,' where open shrublands transition into mature deciduous forests.
Despite their small size, individuals migrate thousands of miles to wintering grounds in Central and northern South America.

Habitat

Early-successional shrublands, brushy field edges, and young forest clearings.

Range

Breeds in the Great Lakes and Appalachian regions; winters in Central America and the northern Andes.
