Taxonomy
The distribution of the Pompadour Green Pigeon is peculiarly disjunct and several of its subspecies are distinctive, leading some authorities to split it into six species:
- Sri Lanka Green Pigeon (Treron pompadora) from Sri Lanka. Monotypic.
- Grey-fronted Green Pigeon (Treron affinis) from the Western Ghats in India. Monotypic.
- Andaman Green Pigeon (Treron chloropterus) from the Andamans and Nicobars. Monotypic.
- Ashy-headed Green Pigeon (Treron phayrei) from northeast India and Nepal, east to Yunnan in China, and south through Indochina (north of the Isthmus of Kra). Commonly considered monotypic, though some recognize the subspecies conoveri.
- Philippine Green Pigeon (Treron axillaris) from the Philippines. Includes the subspecies amadoni, canescens and everetti.
- Buru Green Pigeon (Treron aromaticus) from small islands in the Flores Sea and Buru, Indonesia. Monotypic.
