Gray-and-buff Woodpecker
Hemicircus concretus
Small stout woodpecker with an oversized crested head and black-and-white scaling on the back. Males have a brilliant red front to the crest that females lack. Agile and active, frequently foraging in the upper canopy or on exposed snags. Crawls along trunks, sometimes descending headfirst like a nuthatch. Found in lowland and hill forests. Gives high-pitched squeaks, descending “peer” notes, and rattles.
识别特征
The species has a plump body and short rounded tail, and grows to a length of about 13.5 cm (5.3 in). The head appears large because of the slender neck and the large, cone-shaped crest. The head is largely grey, with a fine white, wavy line running from the cheek to the mantle. In males the forehead is red and the crest grey, while in females, both are grey. Body upper parts and wings are blackish, the feathers being edged with white or buff giving a scalloped effect. Underparts are grey, the tail and underwing dark, and the legs are grey or brown. The beak is long, slender and grey with a black tip, and the iris is chestnut. A gland of unknown function is on the back, the secretions from which sometimes stain the white rump.
分类信息
The grey-and-buff woodpecker was formally described by the Dutch zoologist Coenraad Jacob Temminck in 1821 and given the binomial name Picus concretus. The type locality is western and central Java. The species is now placed in the genus Hemicircus that was introduced in 1837 by the English naturalist William John Swainson.<p>Two subspecies are recognised:<p>The species is sometimes split with H. concretus as the red-crested woodpecker and H. sordidus as the grey-and-buff woodpecker.

分布与栖息地
This woodpecker is native to tropical southeastern Asia. Its range extends from southern Myanmar and peninsular Thailand and Malaysia, to Sumatra and Borneo. It is a resident species found in lowland and mid-elevation evergreen rainforests, particularly clearings and forest edges, also in plantations, bamboo thickets, cleared areas, wooded urban areas and cultivated land.

行为
The grey-and-buff woodpecker is usually seen singly or in pairs, but sometimes occurs in mixed species flocks foraging in the canopy. It mainly feeds by gleaning rather than by drilling into the wood, the diet consisting of insects and fruit, including mistletoe (Loranthus) berries. The birds roost communally at night in shallow holes they excavate near each other in dead wood. Nesting takes place in deeper holes or crevices, the breeding season being between December and July.

Green-backed Flycatcher
Ficedula elisae
A colorful, green-suffused flycatcher. Adult male looks like a faded version of a male Narcissus Flycatcher, with bright yellow eyebrows and underparts; greenish tinge to the upperparts is distinctive and unmistakable. Overall paler and less contrasting patterning, combined with prominent dark eyes, conveys a gentle appearance. Female very similar to female Narcissus, but has a faded-yellow belly and a green-tinged head and back; brighter female Narcissus Flycatchers can have a green tinge, too, but it is usually weaker and restricted to the upper half of the back. Breeds in hilly and submontane mixed broadleaf forests, and winters in open forests and forest edges. Song is a rambling series of somewhat scratchy-sounding warbling notes.
Amethyst-throated Mountain-gem
Lampornis amethystinus
Rather large hummingbird of humid evergreen and pine-oak forest in mountains. Fairly common, but typically inconspicuous in shady understory and at edges, where feeds at all levels on flowers. Despite the exciting name, often looks rather drab and grayish overall with a dark mask, whitish eyestripe, and dusky throat (amethyst gorget rarely catches the light). Note the blackish tail with small, pale gray corners.
Yellow-streaked Warbler
Phylloscopus armandii
Dull brownish leaf warbler. Brown above with brownish-yellow underparts. Extremely similar in appearance to Radde’s Warbler, but Yellow-streaked has a more contrastingly pale brow stripe, finer bill, and fine yellow streaks on the breast. The breast streaks themselves are often not visible, instead appearing as a faint yellow wash from a distance. Dusky Warbler is somewhat similar but is much browner overall with a darker brow stripe and less contrast between upper- and underparts. Breeds in subalpine shrubbery and descends into foothills to winter in similar habitat. Song is a series of cascading tinkling, buzzy notes. Gives metallic “tinks”.
