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.

Trumpeter Swan

Field notes

It is the heaviest flying bird native to North America, with large males sometimes exceeding 30 pounds.
The species was nearly driven to extinction in the early 20th century, with fewer than 70 known wild individuals remaining in 1933.
Unlike the similar Tundra Swan, the Trumpeter typically lacks a yellow spot on the black lore near the eye.
They form long-term monogamous pair bonds, often staying with the same mate for life starting at age 3 or 4.
Their windpipes are exceptionally long and coiled within the breastbone, which allows for their resonant, low-frequency vocalizations.

Habitat

Pristine freshwater marshes, shallow ponds, lakes, and slow-moving rivers with abundant aquatic vegetation.

Range

North America, primarily breeding in Alaska, Western Canada, and the northern United States from the Pacific Northwest to the Great Lakes.
