Choco Tapaculo
Scytalopus chocoensis
A standard Scytalopus tapaculo: plain dark gray with browner flanks and rump. Acts like a mouse, scurrying around on or near the ground within forests. Very difficult to see. Restricted range on west slope of Andes in Colombia and Ecuador. Occurs from around 350–1,000 m elevation, lower than Nariño Tapaculo. Far more often heard than seen. Listen for fairly slow series of piercing “peew” notes, much slower than Nariño.
识别特征
The Chocó tapaculo is 11 cm (4.3 in) long. Males weigh 19 to 22.5 g (0.67 to 0.79 oz) and females 17 to 20.1 g (0.60 to 0.71 oz). The male's mantle is dark gray, its lower back gray with a brown wash, and the rump dark brown with dusky bars. It is lighter gray below to the lower belly, which is reddish-brown with dark bars. The female is similar but the brownish wash extends to the head. The throat is lighter gray than the upper breast; the lower belly sometimes has a yellowish wash. The juvenile's upper parts are drab brown but for the dark brown rump; it appears barred below.
分类信息
The Chocó tapaculo was formerly considered a subspecies of the Nariño tapaculo (Scytalopus vicinior) but was elevated to species status following Krabbe and Schulenberg (1997).

分布与栖息地
The Chocó tapaculo is found in two small areas on the Pacific slope of eastern Panama and separately in a narrow band from western Colombia south into northwestern Ecuador. It principally inhabits the dense understory of humid primary forest but is also found at forest edges. In Panama it ranges in elevation from 1,340 to 1,465 m (4,396 to 4,806 ft) and in Colombia and Ecuador from 250 to 1,250 m (820 to 4,100 ft).

行为
Little is known beyond that the Chocó tapaculo forages on the ground for insects.<p>A female with active gonads was captured in February; nests with juveniles were found in August. A nest was described as a ball of rootlets and moss 12 cm (4.7 in) in diameter hidden in leaf litter. It contained nestlings that were being fed by both adults.<p>The Chocó tapaculo's song is "a very resonant series 5-60 seconds long...the first few notes often slightly lower-pitched and delivered at a faster rate" [1]. The call is a series of short sharp notes [2].

Spectacled Redstart
Myioborus melanocephalus
Attractive warbler of cloud forest and stunted treeline forest in the Andes. Common member of mixed-species flocks. Ranges from far southern Colombia south to Bolivia. Has slaty-gray upperparts, yellow underparts, and bold yellow spectacles. Crown is rufous in the northern half of its range, but solid black in the southern half. Some birds in northern Ecuador and southern Colombia have a yellow forehead. Actively forages along branches, often spreading its tail exposing white outer tail feathers.
Rusty-winged Starling
Aplonis zelandica
A rather small, pale grayish-brown starling, paler on Vanikoro, with a smudgy black patch in front of the eye and distinctive rusty wings. Found in forest and secondary growth, especially montane forest. Similar to Polynesian Starling, but paler above, with a dark eye and more uniform wings. Common call is a melodious “zee-twee.”
Tree Pipit
Anthus trivialis
Slender and streaked pipit. Feeds on the ground like other pipits, but perches readily in trees or bushes when singing, or alights in tree at end of parachuting song flight. As the name suggests, usually associated with trees (on breeding grounds), but also found in agricultural areas and grassy scrub in winter. All pipits look rather similar and are best identified to species by combination of habitat and voice: Tree Pipit call a high, shrill, buzzy "tzzz"; song more melodic and varied than Meadow Pipit song.
