Glossy-black Thrush

About the Glossy-black Thrush

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:

T. s. cumanensis (Hellmayr, 1919) T. s. atrosericeus (Lafresnaye, 1848) T. s. fuscobrunneus (Chapman, 1912) T. s. serranus Tschudi, 1844 T. s. continoi Fraga & Dickinson, 2008 However, as of late 2025, BirdLife International's Handbook of the Birds of the World did not recognize T. s. continoi, including it within T. s. serranus.

Subspecies T. s. continoi had originally been named T. s. unicolor in 1970. 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.
