Peruvian Wren
Cinnycerthia peruana
An accomplished songster found in cloud forest along the east slope of the Andes in northern and central Peru. Some birds are almost entirely brown with faint black barring on wings and tail. Other birds have a variable amount of white on the face and forehead. Plumage is very similar to Sharpe’s Wren, which overlaps with it in northern Peru but is found mainly at lower elevations. In the area of overlap, voice is the best way to separate the two species. Peruvian Wren is often encountered in large family groups that move together through the lower and middle levels of the forest. Pairs sing elaborate duets consisting of rich whistles and trills. They also give rapid, frantic rattles when agitated.
识别特征
The Peruvian wren is 15.5 to 16 cm (6.1 to 6.3 in) long and weighs 19.6 g (0.69 oz). The adults' upperparts are rich chestnut, with the crown and rump being redder. They have a variable amount of white on the face. The tail is also rich chestnut and has narrow black bars. The chin and throat are orange-brown and the chest, belly, and flanks are the same hue but darker. The juvenile is believed to resemble the adult but with no white on the face.
分类信息
What is now the Peruvian wren was formerly called sepia-brown wren and at that time included as subspecies what are now the species Cinnycerthia olivascens and C. fulva. Confusingly, after the split the name sepia-brown wren was transferred to C. olivascens by the International Ornithological Committee (IOC), but the South American Classification Committee of the American Ornithological Society (SACC/AOS) and the Clements taxonomy call it Sharpe's wren. C. fulva is named fulvous wren.<p>The Peruvian wren is monotypic.

行为
The Peruvian wren forages in groups that appear to be extended families. It usually feeds on or near the ground in vegetation and litter, but its diet has not been documented.<p>The Peruvian wren appears to have a protracted breeding season, base on the dates that occupied nests, newly hatched chicks, and fledglings have been observed. One nest has been described; it was a pouch with a down-facing entrance tunnel, constructed of rootlets, moss, and bamboo leaves, and suspended from a bamboo stem.<p>Peruvian wren pairs often sing in duet, "a magnificent series of rich trills and clear whistles" [1]. Its call is "a gravelly, chattering 'ch-d-d-d'" [2].

White-bibbed Babbler
Stachyris thoracica
Handsome and well-named large babbler with a snow-white “bib.” Also note blue facial skin and bright chestnut back. Crown is brownish on birds from western Java, and grayish on those from central and eastern Java. Despite large size and bright colors, can be quite skulky and difficult to see well. Hops and clambers about in dense bushes and vines in foothill forests, typically in mid-sized groups, giving dry churring rattles. Also gives a short, fluty-sounding whistle.
Dark-breasted Rosefinch
Procarduelis nipalensis
Dark medium-sized rosefinch. Male is is dark pink with a lighter throat and eyebrow. Female is dark brown with light wingbars. Both sexes can be similar to Vinaceous Rosefinch, but note male’s different head pattern and female’s unstreaked underparts and noticeable wingbars. Forages on the ground in montane and hill forest, forest edge, and rocky meadows and slopes. Gives a wheezy sparrow-like “wheer.”
Cinnamon Attila
Attila cinnamomeus
Medium-sized sluggish flycatcher of riverine and disturbed habitats. Key marks are entirely cinnamon plumage and large-headed, plain-faced appearance; bill seems heavy and is entirely black. Sits still, peering about, before sallying to foliage for insects. Inhabits mid-story and understory, often at forest edge. Found in forest along rivers and oxbow lakes, in abandoned plantations, and at savanna edges, usually near water. Similar to Dull-capped Attila but has dark eyes and different voice. Most common calls are various mournful whistles.
