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

It is the only warbler species capable of digesting the waxes found in bayberries and wax myrtles, allowing it to winter further north than its relatives.
The species is divided into two main subspecies groups: the 'Myrtle' warbler of the East and the 'Audubon’s' warbler of the West.
Birders frequently refer to this species by the nickname 'Butterbutt' due to its conspicuous yellow uropygial patch.
During migration, they are highly social and often form large, loose flocks with other songbird species.
They are exceptionally versatile foragers, utilizing flycatching, foliage gleaning, and even ground-hopping to find food.

Habitat

Breeds in coniferous and mixed woodlands; winters in various open habitats including brushy fields and suburban parks.

Range

Breeds across Canada and the northern/western US; winters from the southern US through Central America.
