The glossy-black thrush (Turdus serranus) is a species of bird in the family Turdidae. It is found from Venezuela to Argentina. The glossy-black thrush was originally described with its current binomial Turdus serranus. Its further taxonomy is unsettled. The IOC, AviList, and the Clements taxonomy assign it these five subspecies:
Because T. unicolor had been previously assigned to Tickell's thrush, by the principle of priority Fraga and Dickinson proposed its current subspecific epithet. What is now the black thrush (T. infuscatus) was previously treated as another subspecies of T. serranus, but molecular studies in the early 2000s determined that they are separate species and not closely related.
This article follows the five-subspecies model. ��2�... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Glossy-black Thrush is recorded against all the birds logged in Farallones de Cali National Natural Park (148 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.
