Not easy to distinguish from European Honey Buzzard, which overlap in the Middle East[1].

Distribution

Siberia east to Japan and south to Indonesia and The Philippines. Northern populations are migratory

Taxonomy

Considered conspecific with European Honey Buzzard by some authors.

Reference [4] notes that differences in DNA and morphology support a split into 2 species: "Oriental Honeybuzzard" (strict sense), P. orientalis, from subspecies orientalis, philippensis and ruficollis; and "Sunda Honeybuzzard", P. ptilorhynchus from palawanensis, ptilorhynchus and torquatus.

Subspecies

Clements recognises the following subspecies [1]:

  • P. p. orientalis: "Oriental Honeybuzzard". South Siberia to Manchuria and Japan; winters to Greater Sundas
  • P. p. ruficollis: "Oriental Honeybuzzard". India and Sri Lanka to Myanmar and extreme south west China
  • P. p. philippensis: "Oriental Honeybuzzard". North and east Philippine Islands
  • P. p. palawanensis: "Sunda Honeybuzzard". South Philippines (Palawan and Calauit)
  • P. p. torquatus: "Sunda Honeybuzzard". Malay Peninsula, Sumatra and Borneo
  • P. p. ptilorhynchus: "Sunda Honeybuzzard" Java
