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 utilize two distinct song types: one specifically for territorial defense and another for attracting mates.
The species is known for its tireless singing, with one individual recorded singing 466 songs in a single hour.
Despite being a forest interior specialist, it is a frequent and visible migrant in city parks and suburban woodlots.
They are primarily insectivorous, often capturing prey by hovering at the tips of coniferous needles or performing short aerial sallies.
In the western edges of its range, it occasionally hybridizes with the closely related Townsend's Warbler.

Habitat

Breeds in coniferous and mixed forests, particularly those with a high density of hemlock, spruce, or pine trees.

Range

Breeds from western Canada across the northern U.S. and south through the Appalachians; winters in Mexico, Central America, and the West Indies.
