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.

Acre Tody-Tyrant

Hemitriccus cohnhafti

The Acre Tody-Tyrant is a small, olive-toned flycatcher specialized to bamboo thickets in the southwestern Amazon. It was only formally described as a distinct species in 2013 after being distinguished by its unique vocalizations.

What it sounds like

A rapid, dry, mechanical-sounding trill or rattle that typically lasts about one second.

Field notes

It is an obligate specialist of Guadua bamboo, rarely venturing far from dense bamboo stands.
The species was named in honor of Mario Cohn-Haft, a curator at the National Institute of Amazonian Research (INPA).
It is nearly identical in plumage to the Zimmer's Tody-Tyrant but can be reliably identified by its faster, higher-pitched song.
Its formal description was based on specimens and recordings collected near the Purus and Acre rivers.
The bird maintains a small territory and is often difficult to spot as it perches motionless in the mid-story of bamboo tangles.

Habitat

Tropical lowland evergreen forest with thickets of Guadua bamboo.

Range

Southwestern Amazon basin, specifically in Acre (Brazil), Pando (Bolivia), and Madre de Dios (Peru).
