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-crowned Warbler

Basileuterus culicivorus

A small, active Neotropical warbler distinguished by a bright yellow crown stripe bordered by bold black lateral stripes. It is primarily an understory species known for its restless foraging behavior.

What it sounds like

A sharp, high-pitched 'tsit' call; the song is a series of thin, accelerating whistling notes that often rise in pitch.

Field notes

The golden crown stripe is often partially concealed by olive feathers and is flashed primarily during territorial displays or when the bird is agitated.
It is a highly polytypic species with over 10 recognized subspecies, which some taxonomists suggest may represent multiple distinct species.
Unlike many wood-warblers, this species is largely non-migratory, remaining in its tropical or subtropical range year-round.
It frequently serves as a nuclear member of mixed-species foraging flocks, helping to lead other birds through the forest understory.
The nest is a distinctive domed structure with a side entrance, typically built on the ground or a steep bank among leaf litter.

Habitat

Humid evergreen forests, gallery woodlands, and shaded coffee plantations, typically in the lower to middle strata.

Range

Northeastern Mexico through Central America to northern Argentina, Uruguay, and northeastern Brazil.
