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.

Yellow-green Vireo

Vireo flavoviridis

The Yellow-green Vireo is a Neotropical songbird characterized by its bright olive-green upperparts and distinctive yellow wash on its flanks and undertail coverts.

What it sounds like

A series of short, disjointed vireo-like phrases, slower and more hesitant than the Red-eyed Vireo's song.

Field notes

It is a long-distance migrant, breeding in Middle America and wintering primarily in the western Amazon basin.
Unlike the similar Red-eyed Vireo, it lacks the bold black borders on its gray crown and has a noticeably larger bill.
The species is highly dependent on fruit during the winter, though it remains primarily insectivorous during the breeding season.
It was historically treated as a subspecies of the Red-eyed Vireo until taxonomic splits recognized its distinct morphology and song.
While its core range is south of the border, it is a regular but rare summer resident in the riparian woodlands of the Rio Grande Valley in Texas.

Habitat

Lowland tropical forests, gallery forests, scrubby edges, and plantations.

Range

Breeds from southernmost Texas through Mexico to central Panama; winters in South America.
