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

Males exhibit structural coloration, appearing iridescent blue on the head and greenish on the body when viewed in direct sunlight.
Unlike many songbirds that hop, Brewer's Blackbirds walk with a rhythmic, swaggering gait while foraging on the ground.
They are highly adaptable foragers, frequently seen 'patrolling' urban environments like parking lots and outdoor cafes for food scraps.
Nesting is often colonial; a single tree or shrub may host several breeding pairs in a loose aggregate.
The species was named by John James Audubon in honor of his friend and fellow ornithologist Thomas Mayo Brewer.

Habitat

Open landscapes including grasslands, agricultural fields, coastal scrub, and urban parks.

Range

Western and central North America, with wintering populations extending into Mexico and the Gulf Coast.
