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.

Possible
About 20% of wildlife watchers report a Black-billed Thrush sighting in Sierra de la Macarena National Park on a given day, based on 169 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 61st most-seen of the 418 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May and August
In those months about 30% of wildlife watchers report a Black-billed Thrush in Sierra de la Macarena National Park on a given day, against about 10% in January, April, July and September–November, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Black-billed Thrush sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 13
Of the 13 parks where we can rate Black-billed Thrush sightings, Sierra de la Macarena National Park ranks 3rd at about 20%. The best odds are in Farallones de Cali National Natural Park (Colombia, about 70%) and Manu National Park (Peru, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Black-billed Thrush is recorded against all the birds logged in Sierra de la Macarena National Park (169 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.
