Cuzco Brushfinch
Atlapetes canigenis
Dark sparrow-like bird with a restricted range in the Andes of southern Peru. Dark gray with a reddish-orange crown. Forages singly or in pairs on the ground, not usually associating with other species. Extensive gray coloration and red crown distinguish it from other brushfinches within its range. Listen for its song, an emphatic metallic warble: “tseew, suweet.”
识别特征
Brushfinches are typically medium-size sparrows, with long tails. Brushfinches are usually gray or olive in colour with a contrasting crown. Cuzco brushfinches are two-toned with a uniform dusky gray and a rufous crown. The center of the belly, as well as the other underparts, are lighter gray than the outside, which is dark gray and the rufous color extends to the nape. The crown is boarded by a black stripe extending from in front of the eyes until the gray auriculars. The tail and wings are blackish with the primaries margined slightly with a grayish external. There is a slight fulvous or tawny tint to the remiges most external parts.<p>One important note is that the Cuzco brushfinch shows considerable variation with the intensity of gray in the underparts - some almost uniformly dark gray below and others that are pale gray with grayish-white abdomens.<p>Males and females are extremely similar in colour, with the female being slightly smaller.<p>Adults:<p>Male: wing 76 mm (3.0 in), tail 78 mm, tarsus 27 mm (1.1 in), culmen 15.5 mm (0.61 in)<p>Female: wing 72 mm (2.8 in), tail 72 mm, tarsus 25 mm, culmen 15 mm
分类信息
The Cuzco brushfinch is a species in the genus Atlapetes - along with 30 others. This genus is in the under-class Aves, order passeriformes (songbirds) and family Emberizidae. The Cuzco brushfinch has been denoted in 1919 by Chapman as Atlapetes canigenis. <p>In 1938 canigenis was categorized as a subspecies of slaty brushfinch. However, Canigenis is in a clade that contains other taxa of Atlapetes from southern Peru and Bolivia, such as Atlapetes melanolaemus (black-faced brush-finch), Atlapetes melanopsis (black-spectacled brush-finch) and Atlapetes forbesi (Apurimac brush-finch), and is not as closely related to schistaceus as once thought.<p>Remsen and Graves (1995) later predicted that the populations of the slaty brushfinch are not monophyletic but rather have a closer relatedness to the parapatric populations of rufous-naped brushfinch. This species had population distributed from northwestern Venezuela to Bolivia.<p>Many brushfinches occur in this area; for example, A. mfinucha rerborghi, A. schistaceus canigenis and A. mfinucha tnelnizolaernus, which all have a similarly rather poorly developed malar stripe. However this does not imply a close relationship, despite all looking very similar and having a similar habitat. Paynter (1978) hypothesised no close relationship between A. melanolaemus and A. canigenis.

分布与栖息地
The Cuzco brushfinch is native to the Americas. More specifically it is an endemic of south-central Peru where it is found in montane areas of the Andes. The known elevation range for this brushfinch is approximately 2,300–3,600 m (7,550–11,810 ft) above sea level. They are mostly seen in the surrounding areas of Cusco.<p>There is very little information on the specific habitat of the Cuzco brushfinch. They do tend to reside in the humid temperate zone of the Andes, as they thrive in humid montane forest on the slopes.

Shelley's Francolin
Scleroptila shelleyi
Medium-sized, beautifully-patterned francolin. Shows rufous patches in the wings in flight. Found on the ground in areas with thick grass, ranging from pure grassland to lush woodland. Mostly at low and moderate elevations, but sometimes found in high mountain grassland. Call is a rhythmic up-and-down repeated “chil-it, chil-chow”. Generally scarce, shy, and retiring. Range does not overlap extensively with similar francolins. Combination of complex facial pattern and belly heavily barred black-and-white are always diagnostic. Much more cleanly and boldly marked than the more washed-out and buffy Whyte’s Francolin.
Rufous Treepie
Dendrocitta vagabunda
A long- and stiff-tailed bird with primarily rusty-brown upperparts and dull orangish underparts. The head, mantle, and neck region are a dull, sooty black. The long graduated tail is pale gray with a wide black terminal band. Note the conspicuous silvery-gray, white, and black patterns on the wings. The blackish-gray bill is stout with a hooked tip. Found in a wide range of habitats from woodlands to scrubby patches, singly or in pairs feeding in the treetops. The call is a loud metallic “krowwiiii kroo.”
Tufted Tit-Tyrant
Anairetes parulus
Active little bird found in wide variety of scrubby, brushy, and lightly wooded habitats from lowlands to the high Andes. Often in pairs, hopping in bushes and brush with tail often held cocked; can be difficult to see well as it constantly flits about. Best identified by small size, recurved “devil horn” crest, and staring pale eyes; breast streaking finer and less striking than on Yellow-billed Tit-Tyrant, which has limited range overlap with Tufted Tit-Tyrant.
