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.

Eurasian Siskin

Spinus spinus

The Eurasian Siskin is a small, energetic finch characterized by its streaky yellow-green plumage and deeply forked tail. It is a highly social species often observed in acrobatic flocks foraging in the forest canopy.

What it sounds like

A clear, rising 'tsuu' or 'tluih' contact call; the song is a rapid, musical twittering that typically ends in a long, wheezing 'dsuiii' note.

Field notes

Males display a distinctive black crown and chin patch, which are absent in the more dull-colored, streaky females.
Their specialized narrow bills are perfectly adapted for extracting seeds from the small cones of alder and birch trees.
This species is known for irruptive migrations, where large numbers move south or west when food supplies in their northern range fail.
Siskins are exceptionally agile feeders, frequently hanging upside down to reach seed heads similar to the behavior of tits.
During the breeding season, males perform a circular butterfly-like display flight accompanied by a continuous twittering song.

Habitat

Coniferous and mixed woodlands, with a strong preference for spruce, alder, and birch forests.

Range

Widespread across temperate Europe and Asia, ranging from the British Isles to Japan.
