Andaman Woodpecker
Dryocopus hodgei
A large, unmistakable black woodpecker with a red crest. Note the long, dark bill and strikingly pale eyes. Found in mangroves and evergreen forests, where it occurs in pairs or small parties. Prefers feeding higher up, but is known to come down to look for invertebrates. The call is loud, sharp, and shrill, and usually consists of one or two notes.
识别特征
The Andaman woodpecker is around 38 cm (15 in) long and weighs between 156–255 g (5.5–9.0 oz). The plumage is mostly slate-grey to black, with a bright red crest. The male also has a red crown and malar area under the eye. The bare skin around the eye is grey, and the legs are slaty coloured, and the bill is black. The irises are pale yellow. Juvenile birds look like adults but have browner, duller plumage and brown eyes, and may have with feathers in the crown. The species differs from the white-bellied woodpecker in not having a white belly and having more slate-coloured plumage (as opposed to black).
分类信息
The Andaman woodpecker was described by Edward Blyth in 1860 as Mulleripicus Hodgei. The specific name hodgei is for Captain S. Hodge, of the Royal Navy, who was stationed in the Andaman Islands at the time. The species was once considered to be a subspecies of the white-bellied woodpecker, but differs in its appearance and its calls. The separation of the two species is also supported by genetic evidence.

行为
Little is recorded about the behaviour of the Andaman woodpecker. It lives in pairs, but also associates in small flocks. It forages on large trunks and branches, but has also been recorded foraging on the ground for ants. It has been recorded breeding between January and March, and breeds in a nest hole 6–14 m (20–46 ft) off the forest floor, in a dead tree. Two eggs are laid.

Bornean Forktail
Enicurus borneensis
A typical forktail, with piebald plumage and long tail. Black head, upper back, chest and wings; white belly, rump, forecrown and wingbar; black and white tail and pale-pink legs. Inhabits shaded whitewater streams through montane rainforests, along which it perches on boulders and low-hanging branches. May overlap at mid-elevations with the very similar White-crowned Forktail which occurs in the lowlands, but Bornean has a longer tail and less extensive white on the head. Often detected by its vocalizations, a harsh buzzing whistle and high metallic whistles.
White-tailed Nuthatch
Sitta himalayensis
Simply-colored nuthatch with gray upperparts and pale orange underparts. Difficult to distinguish from similarly-colored nuthatches, but averages smaller than Chestnut-bellied Nuthatch, and has a bright white spot on the tail base and a clean tan vent instead of a white-and-orange-striped one. Resides in Himalayan foothills, where it often forages in the middle and upper levels with mixed-species flocks.
Chivi Vireo
Vireo chivi
Plain olive-green above and whitish below with no wingbars. Variable amount of yellow on underparts, sometimes bright lemon on undertail coverts and flanks. Dark stripe through and above eye. Thicker bill than warblers, body about the same size. Widespread through South America, mainly in lowlands but also up into foothills. Very similar to Red-eyed Vireo, best distinguished by voice.
