Tatama Tapaculo
Scytalopus alvarezlopezi
This typical “Scytalopus” tapaculo is found only in Colombia’s western Andes. Plumage is gray with a brown tinge to the rump and faint, rusty barring on the lower underparts. Similar to Nariño Tapaculo, Spillmann’s Tapaculo, and Choco Tapaculo, and is best identified by its distinctive voice. Song is a long, pulsating series of frog-like calls that gradually increases in volume and pitch. Inhabits understory of cloud forest and is normally quite hard to see.
识别特征
The Tatama tapaculo is almost entirely black, though the underparts are grayish black and the rump has a tinge of dark brown. The flanks and lower abdomen have indistinct bars. Its overall length is about 12 cm (4.7 in) and two males weighed 24.0 and 25.4 g (0.85 and 0.90 oz).
分类信息
Though the Tatama tapaculo was first discovered in 1992, it was not formally described until 2017. The South American Classification Committee of the American Ornithological Society accepted it as a new species in May 2019. The International Ornithological Committee followed suit in June 2019 and the Clements taxonomy in July 2019. Its closest relative is the El Oro tapaculo (Scytalopus robbinsi); those two species, Stiles's tapaculo (S. stilesi), and Magdalena tapaculo (S. rodriguezi) form a distinctive clade.<p>The specific epithet honors Colombian ornithologist Humberto Álvarez-López. The English name is taken from Cerro Tatamá, the highest peak in the mountains where the Tatama tapaculo lives.

分布与栖息地
The Tatama tapaculo is found primarily on the west side of the West Andes of Colombia, though it "spills over" to the east side of some ridges. It inhabits dense undergrowth in primary cloud forest but apparently shuns secondary forest. On the west side it is found from about 1,300 to 1,750 m (4,270 to 5,740 ft) elevation but on the east side can be found as high as 2,200 m (7,200 ft).

Orange Ground-Thrush
Geokichla gurneyi
Large, brown-backed, orange-breasted thrush with bold white wingbars. Found in the understory of middle- and high-elevation forest. Generally shy and scarce. The song is musical and typically thrush-like: a chatty and cheerful series of whistles. The call is a very thin, rising trill. Very similar to Abyssinian Ground-Thrush, but has a different pattern on the head: an olive crown, black bar below the eye, and a broken white eye ring.

Marsh Tit
Poecile palustris
Plain tit with a grayish-brown body and contrasting black-and-white head pattern. Very similar to Willow Tit and difficult to separate, but note the general lack of a prominent wing panel, smaller-headed appearance, and smaller, neater bib. These criteria, however, are generally more reliable in western European range than in Asian range. Inhabits deciduous woodland, older orchards, and gardens; sometimes visits bird feeders. Voice is diagnostic in western Europe, but much less so in Asia; song is a repetitive series of “chew” notes (essentially a slow trill) and calls include a bright “pitchu, pitchu” and “tsiptsip.” Favors deciduous wooded habitat.

Golden-winged Sparrow
Arremon schlegeli
Beautiful black-helmeted sparrow of forest understory. Contrasting black head, bright yellow bill, white throat and underparts, light gray mantle, yellow-green back and rump, gray wings and tail, and golden shoulders. Female has duller bill and buff-tinged underparts. Found alone or in pairs foraging in the understory of dry to humid forest and scrubby second growth. Vocalization is a high pitched “zeut, zeut, zeee.” The only totally black headed sparrow in its range. Found only in Colombia and Venezuela.
