and the grey-fronted green pigeon but has no maroon on the wing. The male does not have any grey on the head but has a narrow band of lilac on the upper breast with a broader orange band below. The undertail-coverts are cinnamon with the longer feathers edged yellow. The tail is grey above with a broad subterminal dark band. The females are yellow below and lack the orange or lilac bands. The undertail coverts are duller cinnamon with greenish spots. The upper tail however has the central feathers slaty grey rather than green as in females of ''T. affinis'' or ''T. pompadora''. The Sri Lankan population (''T. b. leggei'') is slightly smaller in wing length but otherwise similar. Other populations that have been named as subspecies include ''domvilii'' (Swinhoe, 1870) of Hainan Island and ''javana'' Robinson & Kloss, 1923 from Java and Bali. Population ''praetermissa'' from Thailand is often included in the nominate form.

Habitat and distribution

This is a species of forest and is widely distributed from the Terai and lower Himalayas (below ) south mainly in the Western and Eastern Ghats and in Sri Lankan forests not far from the coast. They are found in Burma, Thailand the Malay Peninsula, Vietnam, Java and Hainan. Some seasonal movements are suspected as vagrants have been recorded from locations like Sind.

They are known to feed on '' Strychnos nux-vomica'', the fruits of which are toxic to mammals. They are sometimes seen on the ground. Their call is a low subdued series of modulated wandering whistles. Males fight with each other during the breeding season, slapping each other with their wing and pecking each other.
