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.

Floreana Mockingbird

Mimus trifasciatus

The Floreana Mockingbird is a critically endangered, large passerine notable for its historical role in shaping Charles Darwin's theories of evolution. It is distinguished by its curved bill and dark patches on the sides of its breast.

What it sounds like

A loud, melodious series of varied whistles and musical phrases, interspersed with harsh, guttural 'chuck' alarm notes.

Field notes

It was the first mockingbird species Charles Darwin noticed differed between islands, serving as a primary catalyst for his thoughts on natural selection.
The species is extinct on its namesake island of Floreana and survives only on two tiny satellite islets: Champion and Gardner-by-Floreana.
They exhibit a complex cooperative breeding system where family groups help a dominant pair defend territory and raise fledglings.
The total global population is highly volatile, often fluctuating between 50 and a few hundred individuals depending on rainfall and food availability.
Highly opportunistic feeders, they have been observed drinking the blood of sea lions and eating the eggs of nesting seabirds.

Habitat

Arid lowland scrubland dominated by Opuntia cacti and scattered deciduous trees.

Range

Restricted to the islets of Champion and Gardner-by-Floreana in the Galápagos Archipelago, Ecuador.
