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

European Greenfinch

Chloris chloris

A stocky, thick-billed finch recognized by its olive-green plumage and vibrant yellow flashes on the primary feathers and tail edges.

What it sounds like

A complex medley of liquid trills and twittering, most famously punctuated by a long, nasal, drawn-out 'dzwee' wheeze.

Field notes

The species is highly susceptible to trichomonosis, a parasitic disease that has led to significant regional population declines.
During the breeding season, males perform a distinctive 'butterfly' display flight characterized by slow, deep wingbeats.
Their powerful conical beaks are specialized for cracking open tough seeds, including those from sunflowers and rosehips.
While primarily granivorous, they supplement their diet with aphids and other small insects during the nesting period.
They are highly gregarious in winter, often forming large foraging flocks with other finch species in agricultural fields.

Habitat

Woodland edges, hedgerows, orchards, and suburban gardens with dense shrubbery.

Range

Widespread throughout Europe, North Africa, and Southwest Asia; introduced populations exist in Australia and New Zealand.
