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 Tree Sparrow

Passer montanus

A small, gregarious passerine distinguished from the House Sparrow by its solid chestnut crown and a distinctive black patch on each white cheek.

What it sounds like

A high-pitched, metallic 'tschip' or 'chup' that is generally shriller and more musical than the House Sparrow's call.

Field notes

Unlike the House Sparrow, this species is sexually monomorphic, meaning males and females have identical plumage.
A small, stable population exists in the United States, descended from just 12 birds released in St. Louis, Missouri, in 1870.
They are obligate cavity nesters, frequently utilizing tree hollows, nest boxes, or crevices in stone walls and buildings.
In East Asia, this species replaces the House Sparrow as the primary urban-dwelling sparrow, living in close proximity to humans.
During the breeding season, they shift from a granivorous diet to hunting insects to provide necessary protein for their altricial chicks.

Habitat

Lightly wooded areas, farmland, orchards, and urban parks with sufficient nesting cavities.

Range

Widespread across temperate Eurasia and Southeast Asia; introduced populations in Australia and the Midwestern United States.
