Molecular phylogenetics studies published in the 2010s determined that arthuri and murinus should again be established as full species. Following those studies, the South American Classification Committee, the IOC, AviList, and the Clements taxonomy recognized them as the campina thrush and pantepui thrush respectively. With these moves the systems returned the black-billed thrush to its early twentieth century status with three subspecies.

GBIF citizen-science records
It is estimated from how often the Black-billed Thrush is recorded against all the birds logged in Tambopata National Reserve (213 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
