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.

Birdsong field guide

Wrentit

Chamaea fasciata

A small, secretive, and highly sedentary songbird of the Pacific coast, the Wrentit is the sole North American representative of the sylviid babblers.

What it sounds like

A series of loud, clear whistles on a single pitch that accelerates into a trill, resembling a bouncing ping-pong ball.

Field notes

It is the only member of the family Sylviidae (sylviid babblers) native to the New World.
Wrentits are notoriously sedentary, rarely dispersing more than 400 meters from their natal territory.
Pairs are strictly monogamous and stay together year-round, often for their entire lives.
The species has a distinctive pale, yellowish-white iris that provides a striking contrast to its drab plumage.
Despite their bird-like name, they are more closely related to Old World warblers than to wrens or tits.

Habitat

Dense chaparral, coastal sage scrub, and thick riparian underbrush.

Range

Pacific coast of North America, ranging from western Oregon to northern Baja California.
