The black-billed thrush (Turdus ignobilis) is a species of bird in the family Turdidae. It is found in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela. The black-billed thrush was originally described in 1858 with its current binomial Turdus ignobilis. Its further taxonomy is unsettled.
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 Santa Cruz de la Sierra on a given day, based on 85 verified sightings from GBIF citizen-science data. It is the 54th most-seen of the 208 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.
January
In that month about 50% of wildlife watchers report a Black-billed Thrush in Santa Cruz de la Sierra on a given day, against under 5% in May and September, the lowest months. That is one of Santa Cruz de la Sierra's wettest months, with about 170 mm of rain against 40 mm in July.
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.
4th of 4
Of the 4 cities where we can rate Black-billed Thrush sightings, Santa Cruz de la Sierra ranks 4th at about 20%. The best odds are in Medellín (Colombia, about 70%), Cali (Colombia, about 60%) and Manaus (Brazil, about 30%).
GBIF citizen-science records
It is estimated from how often the Black-billed Thrush is recorded against all the birds logged in Santa Cruz de la Sierra (85 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.
