Superciliated Wren
Cantorchilus superciliaris
This brown-and-white wren has an amazingly loud voice for its size. It inhabits dry forest and scrub in western Ecuador and northwestern Peru. Note the barred wings and tail, white throat and face, and dark stripe behind the eye (which is inconspicuous on some birds). Usually stays inside dense tangles, where it can be especially hard to see during the rainy season after the vegetation leafs out. Gives a large variety of far-carrying songs and calls.
识别特征
The superciliated wren is 14.5 cm (5.7 in) long. Adults of the nominate subspecies have a dark grayish brown crown, rufous-brown shoulders and back becoming redder on the rump. The tail is reddish brown with black bars. They have a prominent white supercilium, a dark brown stripe through the eye, and buffy-white cheeks. Their chin and throat are pale buffy white that darkens to the lower chest and the flanks are buffy gray. Juveniles are similar but a cooler brown in the uppersides. C. s. baroni has a more tawny lower back and rump.
分类信息
The superciliated wren has sometimes been treated as conspecific with the buff-breasted wren (C. leucotis) but they differ in vocalizations and ecology. It has two subspecies, the nominate C. s. superciliaris and C. s. baroni.

分布与栖息地
The nominate superciliated wren is found in western Ecuador from Manabí Province south to Guayas Province. C. s. baroni is found from southern Ecuador's El Oro and Loja Provinces south to the departments of Ancash and Lima in west central Peru. The species primarily inhabits dry woodland, scrub, and brushland though it is also found in more humid woodland. In elevation it mostly ranges from sea level to 1,500 m (4,900 ft) but can be found as high as 1,850 m (6,070 ft).

行为
The superciliated wren forages in vegetation on and near the ground, usually in pairs. Its primary food appears to be insects.<p>The superciliated wren's breeding period is not well known; at a minimum it includes January and February in Peru. Its nest is rather flimsy and shaped like a flask. Pairs build several nests but use only one for breeding; it is lined with soft material. Nests are typically placed 1.6 to 3.2 m (5.2 to 10.5 ft) above ground in a bush or tree. Two or three eggs are laid. Nests are frequently parasitized by shiny cowbirds (Molothrus bonariensis).<p>Both sexes of the superciliated wren are thought to sing "a series of short repeated phrases of 2 or 3 notes" with sometimes a trill added.

Long-billed Tailorbird
Artisornis moreaui
Inconspicuous, apalis-like grayish warbler with a long tail, straight thin bill, and buff-brown forehead. Isolated population in Mozambique, sometimes considered a different species (Njesi Tailorbird), is smaller, darker, and browner on the head. Singles and pairs are very low density, shy and creep slowly through the undergrowth and canopy, especially nearby streams; sometimes joins mixed-species flocks. Song a pleasant sweet bouncing “eeh-yuh, eeh-yuh, eeh-yuh” or strident “peelik-peelik-peelik”, sometimes joined in duet with a dry buzzing “dzit”; call a high-pitched “chhet” like a squeaky dog’s toy. Similar Brown-headed Apalis is shorter-billed than Long-billed Tailorbird and has white tips to the tail.
Blackthroat
Calliope obscura
A somberly-colored robin which breeds in dense bamboo thickets. Male is slate-gray above (only a hint of blue may be detected in good lighting) with a white belly and black bib. Female is brown with a paler belly and a rusty-brown tail. Forages on the ground and in low bushes like most other small robins. Shy, usually keeping close to cover. Song is a series of distinct, separated phrases consisting of bright fluid warbling, high buzzy trills, and buzzy warbling.
Antipodes Parakeet
Cyanoramphus unicolor
Entirely green parakeet endemic to the subantarctic Antipodes Islands. The largest of New Zealand’s native parakeets. Males are larger than females. Common throughout their habitat and range, walking and climbing through vegetation when foraging. Will scavenge bird carcasses. An inquisitive bird, often approaching human visitors. Call is a distinctive deep “kok-kok-kok-kok” chatter. Shares its range with Reischek’s parakeet, but distinguishable by much larger size and lack of a red crown.
