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 30% of wildlife watchers report a Black-billed Thrush sighting in Manaus on a given day, based on 141 verified sightings from GBIF citizen-science data. It is the 18th most-seen of the 116 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
April and August
In those months about 40% of wildlife watchers report a Black-billed Thrush in Manaus on a given day, against about 10% in September, the lowest month.
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 4
Of the 4 cities where we can rate Black-billed Thrush sightings, Manaus ranks 3rd at about 30%. The best odds are in Medellín (Colombia, about 70%) and Cali (Colombia, about 60%).
GBIF citizen-science records
It is estimated from how often the Black-billed Thrush is recorded against all the birds logged in Manaus (141 verified sightings), 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.
