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.

Clarion Wren

Troglodytes tanneri

The Clarion Wren is a large, island-endemic songbird closely related to the House Wren but distinguished by its significantly longer bill and larger body. It is the only resident passerine on the remote volcanic outpost of Clarion Island.

What it sounds like

A rich, bubbling series of musical whistles and trills, similar to the House Wren but generally louder and more deliberate.

Field notes

It is strictly endemic to Clarion Island in the Revillagigedo Archipelago, located about 700 kilometers off the Mexican coast.
Evolutionarily, it diverged from the House Wren lineage approximately 100,000 to 200,000 years ago.
The species possesses a notably longer and more decurved bill, adapted for foraging in volcanic crevices and dense scrub.
Its population is extremely vulnerable to habitat degradation caused by invasive species, particularly feral rabbits and sheep.
Unlike many wrens, it is often found foraging openly on barren lava flows and among prickly pear cacti.

Habitat

Dense maritime scrub, volcanic rock crevices, and patches of Opuntia cactus.

Range

Clarion Island, Mexico.
