Black-backed Bush Tanager
Urothraupis stolzmanni
Distinctive tanager found only at high elevations in the Andes. It has black upperparts, white throat and breast, gray belly, and a rather small bill. Sexes look alike. Typically encountered in small groups that forage actively in stunted forest and dense scrub near treeline, often with mixed species flocks.
分类信息
The black-backed bush tanager was formally described in 1885 by Władysław Taczanowski and Hans von Berlepsch from specimens collected by the Polish zoologist Jan Sztolcman (sometimes written Jean Stolzmann) on the eastern slopes of the Tungurahua Volcano in central Ecuador. The ornithologists introduced the monospecific genus Urothraupis and coined the binomial name Urothraupis stolzmanni. The genus name combines the Ancient Greek oura meaning "tail" with thraupis, an unidentified small bird, used by ornithologist for tanagers. The specific epithet honors the collector Sztolcman/Stolzmann. A 2014 molecular phylogenetic study of the tanager family Thraupidae found that the black-backed bush tanager is a member of the subfamily Poospizinae and has a sister relationship to the pardusco in the monospecific genus Nephelornis. The black-backed bush tanager is monotypic: no subspecies are recognised.

Thick-billed Vireo
Vireo crassirostris
A small loquacious inhabitant of scrubland, thickets, and brushy forest edges where it typically feeds within dense cover. The similar White-eyed Vireo can be distinguished by its smaller bill, greener back, and bright yellow sides; furthermore, adults have white, not dusky, eyes. The Cuban Vireo lacks the Thick-billed Vireo’s bold wingbars. The song is a scratchy jumbled “chick, didderwid-weee-zhee, chip” or variations thereof. Calls include a “zhip” given singly or in short bursts, a drawn-out harsh “zzhhe,” and a variety of chattering sounds.

Firethroat
Calliope pectardens
Male is stunning, with a metallic blue back, a black mask extending down to the shoulder, and a burning flame-orange throat and breast. Female is plain brown and very difficult to distinguish from female Indian Blue Robin (which generally breeds at lower altitudes than Firethroat) and Siberian Blue Robin (which overlaps with Firethroat only on migration); look out for the female Firethroat’s relatively brighter white throat, darker underparts, and lack of scaling on the breast. The species is shy, keeping to the undergrowth, but will emerge into the open to sing; song is repetitive and pleasant, with imitations and deeper notes thrown in. Breeds in dense, low montane vegetation; winters in similar habitat in lower foothills.

Boyaca Antpitta
Grallaria alticola
Medium-sized antpitta found in elfin forest and páramo near or above treeline in the Andes in north-central Colombia. Typical antpitta shape: plump with short tail and long legs. Dull brownish plumage, darker olive above and richer buffy below. Sexes similar. Fairly common and much more conspicuous than most other antpittas; frequently seen bounding around in the open, though typically close to shrubby cover. Sometimes sings from a fairly prominent perch; listen for series of four to six clipped, piping whistles: usually two higher, longer notes followed by a slightly quicker series of shorter rising notes.
