The thick-billed green pigeon (Treron curvirostra) is a species of bird in the family Columbidae.
Taxonomy[edit]
The thick-billed green pigeon was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other doves and pigeons in the genus Columba and coined the binomial name Columba curvirostra.[2] Gmelin based his description on the "Hook-billed Pigeon" from the "island of Tanna in the South Seas" that had been described and illustrated in 1783 by the English ornithologist John Latham.[3] Latham was mistaken in believing that his specimen had come from the island of Tanna in the New Hebrides. The type locality was designated as the Malay Peninsula by Harry C. Oberholser in 1912.[4][5][6] The thick-billed green pigeon is now placed with around 30 other green pigeons in the genus Treron that was introduced in 1816 by the French ornithologist Louis Pierre Vieillot.[7][8] The genus name is from the Ancient Greek trērōn meaning "pigeon" or "dove". The specific epithet curvirostra combines the Latin curvus meaning "curved" with -rostris meaning "billed".[9]
Nine subspecies are recognized:[8]
- T. c. nipalensis (Hodgson, 1836) – central Nepal and northeast India through Myanmar to south Indochina
- T. c. hainanus Hartert, EJO & Goodson, 1918 – island of Hainan (off southeast China)
- T. c. curvirostra (Gmelin, JF, 1789) – Malay Peninsula and Sumatra
- T. c. haliplous Oberholser, 1912 – Simeulue (west of north Sumatra)
- T. c. pegus Oberholser, 1912 – Nias (west of north Sumatra)
- T. c. smicrus Oberholser, 1912 – Sipura, Siberut and Batu Islands (west of central Sumatra)
- T. c. hypothapsinus Oberholser, 1912 – Enggano Island (west of south Sumatra)
- T. c. nasica Schlegel, 1863 – Borneo
- T. c. erimacrus Oberholser, 1924 – Mindoro and Palawan group (northwest, southwest Philippines)
