Green Iora
Aegithina viridissima
A medium-sized canopy-dweller of lowland and foothill forests, often seen with mixed flocks. Male is dark olive-green with boldly black-and-white-striped wings; female is paler, with an olive back and a less contrasting wing pattern. Look for bright yellow “goggles” around dark eyes in both sexes; Common Iora lacks these goggles and has pale eyes, but these can be hard to discern. Song is high, simple, and repetitive: “wit-dee, wit-dee, wit-dee” or “chew-a-wee-chew, chew-a-wee.” Calls vary, but the most common ones are downslurred and rather nasal-sounding.
识别特征
The green iora is 12–14 cm (4.7–5.5 in) long. The male has black lores and bright yellow "eyelids" (a broken eye-ring). 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.
分类信息
This species was described as Jora viridissima by Charles Lucien Bonaparte in 1850. Harry C. Oberholser described subspecies Aegithina viridissima thapsina from the Anamba Islands in 1917, noting its larger size and yellower plumage. These two subspecies are recognised by the IOC World Bird List, while Aegithina viridissima nesiotica described by Oberholser in 1912 is now included in the nominate subspecies.

分布与栖息地
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.

行为
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.

其他鸟类
Black-hooded Antshrike
Thamnophilus bridgesi
Antshrikes have large, flat heads and large, hooked bills; they often angle their tails downward, below the line of the body. Male Black-hooded is mostly black with a slightly paler belly; note small white spots on the shoulder. The female is paler gray overall with whitish streaking on the head and breast. Most often seen in pairs in the understory of forest and edges. Follows mixed flocks. Listen for accelerating chuckle with a longer raspy note at the end.
Sooty Oystercatcher
Haematopus fuliginosus
Heavy-set shorebird with entirely black plumage and long, thick reddish bill. It has a distinctive fleshy red or yellow eye-ring and very thick pale-pink feet and legs. Exclusively coastal, where it can be found walking around on the edge of rocky headlands, on rock shelves, and along rocky beaches on small islands. Typically found in pairs or small groups. Its call is a loud slow whistled "chew", or when agitated a rapidly repeated "squeaky toy" call.
Mountain Fulvetta
Alcippe peracensis
A plain fulvetta, fairly similar in appearance to the “Gray-cheeked Fulvettas”. Range of the northern subspecies overlaps slightly with that of Yunnan Fulvetta, from which it can be distinguished by duller, more olive-green upperparts, a bolder black line above the eye, and colder gray-washed underparts. Southern subspecies, found in peninsular Malaysia and southern Thailand, is richer brown above with a whiter belly. Fast twittering song is comparable to that of Yunnan Fulvetta but somewhat quicker and shorter. Dry churring rattles are likewise similar to those of Yunnan Fulvetta. Despite its name, does not necessarily inhabit higher altitudes than Yunnan Fulvetta, and altitudinal ranges do overlap.
