Tepui Wren
Troglodytes rufulus
Small, rufous-brown bird of tepui undergrowth. Readily identified by small size, rufous-brown plumage, buffy eyebrow, and (at close range) black barring on wings and tail. Occurs in mossy forest understory and stunted forest at middle and high elevations of the tepui region. Usually remains in dense cover and can be difficult to see, but it will sing from exposed perches. Found in pairs, which forage for insects on and near the ground and typically do not join mixed-species flocks. Song is a high, metallic pair of notes slurred together, the second note lower-pitched, repeated at length and sometimes extended into a tinkling, jumbled series. Calls are harsh scolds reminiscent of other wrens. Distinguished from Flutist Wren (only other wren in range) by strongly rufous coloration and buffy eyebrow.
识别特征
The nominate subspecies of tepui wren is 11.5 to 12 cm (4.5 to 4.7 in) long and weighs 13 to 18 g (0.46 to 0.63 oz). The adult's crown and upperparts are chestnut brown that is slightly redder on the lower back and rump. Its tail is dark reddish brown with thin blackish bars. It has a yellowish buff supercilium and a dark brown streak behind the eye. The throat and breast are yellowish buff; the sides, flanks, and lower belly are reddish brown; and the vent area is buffy brown with dark brown bars. The juvenile is darker with scaly underparts. T. r. fulvigularis is darker and less reddish than the nominate. T. r. yavii has white underparts. T. r. duidae has whitish underparts and the bars on its tail are more pronounced. T. r. wetmorei is the most similar to the nominate, differing only by having gray central underparts. T. r. marahuacae is similar to wetmorei but is smaller and the entire belly is gray.
分类信息
The tepui wren has often been treated a subspecies of mountain wren (Troglodytes solstitialis). The South American Classification Committee of the American Ornithological Society (SACC/AOS) considers those two, ochraceous wren (T. achraceus), rufous-browed wren (T. rufociliatus), and Santa Marta wren (T. monticola) to be a superspecies.<p>The tepui wren has six subspecies:

分布与栖息地
The subspecies of tepui wren are distributed thus:<p>The tepui wren inhabits humid forest, forest edges, and bushland on isolated flat-topped mountains called tepuis. In elevation it ranges from 1,000 to 2,800 m (3,300 to 9,200 ft) but is mostly found in the narrower band between 1,600 and 2,400 m (5,200 and 7,900 ft).

White-eyed Robin
Pachycephalopsis poliosoma
A medium-sized bird of mid-montane forest understory. Sooty gray color, paler on the belly, darker on the face and wing. Note the pale eye and white throat contrasting with the dark face. Birds on the Huon Peninsular have a gray throat. Perches on low branches, flicking tail and scanning the ground for insect prey. Smoky and Blue-gray Robins have limited altitudinal overlap, but White-eyed is usually found at lower elevations, has a white eye and usually a white throat. Voice, a loud, upslurred whistle “wit!”. Also, a rising series of notes, first whistled then becoming raspier and accelerating.
Brownish-flanked Bush Warbler
Horornis fortipes
Small brown warbler of middle elevations, usually retiring and seldom venturing far from the bushes and short trees from which it gives its distinctive song. Rich, dark brown above and paler gray-brown below, with tawny-brown flanks and pale supercilium. Song a resonant, long whistle followed by a short burst of sharp, bright notes, similar to songs of much larger Manchurian and Japanese Bush Warblers but the whistle is much longer and the following notes not as soft and mellow. Endemic Taiwan subspecies (robustipes) sometimes considered species, called Strong-footed Bush Warbler.
Kai Cicadabird
Edolisoma dispar
A thrush-sized songbird. Male is entirely glossy-black, while distinctive female has a gray head, a brown back, and a buff underside with extensive barring. Singles, pairs, or small groups inhabit the canopy of forests, edges, and woodlands, from lowlands into foothills. Sometimes joins mixed-species flocks. Differs from Black-faced Cuckooshrike in lacking a clearly demarcated black face. Male is smaller and slimmer-billed than Wallacean Cuckooshrike. Song is a low, three-note rasping “gek-grrrt-grrrt.” Also gives a high-pitched “whit” call.
