Luzon island-thrush (Turdus thomassoni) is a species of passerine in the family Turdidae. It is endemic to the island of Luzon in the Philippines. It was formerly considered to be two separate subspecies of Island thrush until 2024 when it was classified as a distinct species by the IOC and Clements checklist.[2][3]

Taxonomy

edit

The Luzon island-thrush was first described as Merula thomassoni by ornithologist Henry Seebohm in 1894.[4] In 1907, the subspecies T. t. mayonensis was described as Merula mayonensis by ornithologist Edgar Alexander Mearns, its binomial name being a reference to the mountain where it was first collected, Mount Mayon. Both were later considered to be subspecies of Island thrush as T. p. thomassoni and T. p. mayonensis. In 2024 the two subspecies were classified as one distinct species based on morphological and phylogenic evidence following a 2023 study.[5]

The Luzon island-thrush has two recognized subspecies:[6]

  • T. t. thomassoni (Seebohm, 1894) - Mountains of northern Luzon
  • T. t. mayonensis (Mearns, 1907) - Mountains of southern Luzon
