Thrushes (Turdidae)

Glossy-black Thrush (Turdus serranus) - HBW 10, p. 672

French: Merle lustré German: Samtdrossel Spanish: Mirlo Serrano
Other common names: Black Ouzel

Taxonomy: Turdus serranus Tschudi, 1844, Peru.
Formerly included T. infuscatus as a race, but that species rather smaller and with different song and female has distinctive underwing-coverts. Birds from Argentina (Jujuy) described as race unicolor, but that name invalid, as preoccupied, and no replacement proposed; included in race serranus. Four subspecies recognized.

  • atrosericeus (Lafresnaye, 1848) - NE Colombia and N Venezuela.
  • cumanensis (Hellmayr, 1919) - NE Venezuela.
  • fuscobrunneus (Chapman, 1912) - C & S Colombia and Ecuador.
  • serranus Tschudi, 1844 - Peru, W Bolivia and NW Argentina.
