About Aegithina viridissima (Bonaparte, 1850)
Aegithina viridissima, commonly called the green iora, measures 12–14 cm (4.7–5.5 in) in total length. Males have black lores and a broken bright yellow eye-ring referred to as "eyelids". Their face and upperparts are dark olive, with black wings that have two white wing-bars on the covert feathers and olive-yellow margins on the flight feathers. Their underparts are also dark olive, with lighter flanks and a yellow centre belly, and a black tail. Eye colour ranges from dark to red brown, the beak is grey-blue, and the feet are slaty blue. Females have yellow lores and a complete eye-ring, with medium olive upperparts and tail. Their wings follow a similar pattern to males but are tinged olive, and the wing-bars are yellow instead of white. Female underparts are olive green with a yellow tint on the centre belly. Juvenile green ioras resemble females, but have paler overall plumage. This species is distributed across Tenasserim, the Thai-Malay Peninsula, Sumatra, Borneo, and some small neighbouring islands, and it is classified as locally extinct in Singapore. It inhabits the canopy of lowland forests up to 820 m (2,690 ft) in elevation, and also occurs in tall secondary forest, peat swamp forest, and mangrove forest.
