The green iora (Aegithina viridissima) is a species of

habitat loss, and the International Union for Conservation of Nature
(IUCN) has assessed it as near-threatened.

Taxonomy

This species was described as Jora viridissima by

nominate subspecies.[5]

Description

The green iora is 12–14 cm (4.7–5.5 in) long.[6] The male has black lores and bright yellow "eyelids" (a broken eye-ring).[6][7] The face and upperparts are dark olive. The wings are black, with two white wing-bars on the covert feathers and olive-yellow margins on the flight feathers. The underparts are also dark olive, with lighter flanks and a yellow centre belly. The tail is black. The eyes are dark to red brown, the beak is grey-blue, and the feet are slaty blue. The female has yellow lores and a complete eye-ring. The upperparts and tail are medium olive. The wings are similar to those of the male but are washed olive, and the wing-bars are yellow instead. The underparts are olive green, with a yellow tint on the centre belly. The juvenile bird is similar to the female, but is paler.[7]

Distribution and habitat

This species is found in Tenasserim, the Thai-Malay Peninsula, Sumatra, Borneo and some small neighbouring islands, and it is

locally extinct in Singapore. It lives in the canopy of lowland forests up to 820 m (2,690 ft) in elevation, and is also found in tall secondary forest, peat swamp forest and mangrove forest.[7]

Behaviour

This iora often occurs in pairs or small groups. It feeds on invertebrates, regularly joining mixed-species foraging flocks. The contact call is a whining, descending ji-sheur or ji-wier, and a ji-jirijiri-jeh mating call has been recorded. The green iora is usually sociable, but intense fighting has also been observed. Breeding has been recorded in April and May. The cup-shaped nest is built on a tree 8–12 m (26–39 ft) above the ground. Both the male and female incubate the eggs, and nestlings are brooded in rainy weather. Moulting has been recorded in July and August.[7]

Status

The population is probably declining because of habitat loss caused by

land conversion. The IUCN Red List has assessed it as a near-threatened species.[1]
