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.

Field notes

The species exhibits sexual dimorphism, with males possessing a distinctive blackish head mask that is much duller or brownish in females.
It possesses a powerful conical bill specifically adapted for dehusking seeds and cracking hard conifer nuts.
During the breeding season, males perform a 'butterfly-like' display flight involving slow, deep wingbeats to attract mates.
They are known to be altitudinal migrants, descending from high mountain slopes to lower valleys and agricultural areas during winter.
Nests are typically cup-shaped structures built from moss, lichen, and roots, hidden securely in the branches of trees or shrubs.

Habitat

Montane forests, secondary growth, scrub, and agricultural edges at elevations typically between 1,200 and 3,000 meters.

Range

Southwestern China, Eastern Myanmar, Northern Laos, Northern Vietnam, and Northeastern Thailand.
