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.

Niceforo's Wren

Thryophilus nicefori

The Niceforo's Wren is a critically endangered passerine endemic to the arid canyons of north-central Colombia, distinguished by its bold facial markings and melodic duets. It is a large, terrestrial-foraging wren restricted to a very small and fragmented range.

What it sounds like

A rich, flute-like series of liquid whistles and gurgles, often delivered as a perfectly synchronized duet.

Field notes

It was historically considered a subspecies of the Rufous-and-white Wren but is now classified as a distinct species.
The species is named in honor of Brother Nicéforo María, a prominent French-Colombian naturalist and educator.
It is one of the most threatened birds in the world, with a global population estimated at fewer than 500 individuals.
Pairs engage in complex antiphonal duetting, where the male and female alternate notes so precisely it sounds like a single bird.
The primary threat to its survival is habitat conversion for goat grazing and tobacco cultivation within the Chicamocha Valley.

Habitat

Tropical dry forest and arid scrub dominated by acacia and cacti, particularly in deep river canyons.

Range

Endemic to the Chicamocha and Sogamoso River basins in the department of Santander, Colombia.
