Bearded Mountaineer
Oreonympha nobilis
Fairly large hummingbird with a striking facial pattern and a long tail. Brown above, white below, with a brown head and black-and-white forked tail. Males have an iridescent green and purple gorget, and in some populations a blue forehead; females are similar but duller. Found in dry mountain scrub at high elevations.
Identification
The bearded mountaineer is 14 to 16.5 cm (5.5 to 6.5 in) long including the approximately 2.3 cm (0.91 in) long bill. It weighs about 7 to 9 g (0.25 to 0.32 oz). Adult males of the nominate subspecies have a deep purplish blue forecrown and crown with a narrow black stripe in the middle. The face is bronzy black with a narrow white band at the back. Its gorget is long and narrow, emerald green under the chin and the rest purplish with a bluish tip. The nape, back, and rump are bronzy to bronzy brown. The tail is long and deeply forked; the feathers are bronzy with increasing amounts of white from the innermost to outermost. The center of the breast is white, the sides of the breast and flanks brownish, and the undertail coverts are bronzy brown. The adult female is similar to the male but duller overall and dingier underneath. Its gorget is smaller and mostly white and the tail less deeply forked. Both sexes have black bills and legs. Juveniles are duller than the adults, with a scaly green crown, a dull brown throat, and a yellow mandible.<p>Males of subspecies O. n. albolimbata has white bands on either side of the crown and its tail is much more coppery. The female has white extending from the same white bands of the crown through the lores to the gorget.
Taxonomy
The ornithologist John Gould described the species in 1869, from a specimen collected by Henry Whitely at Tinta District, and placed it in its own genus Oreonympha. He recognised a kinship with Oxypogon and Ramphomicron. A study of mitochondrial DNA of hummingbirds shows it to be most closely related to the bearded helmetcrests (Oxypogon sp.) and the rufous-capped thornbill (Chalcostigma ruficeps). The other member of the genus Chalcostigma lay outside the group, suggesting the genus might need revising in the future. In addition, the South American Classification Committee (SACC) of the American Ornithological Society is considering a proposal to merge both Oreonympha and Chalcostigma into Oxypogon.<p>The SACC, the International Ornithological Committee (IOC), and the Clements taxonomy recognize two subspecies, the nominate O. n. nobilis and O. n. albolimbata. However, BirdLife International's Handbook of the Birds of the World (HBW) treats these taxa as separate species, the eastern and western mountaineers respectively.

Range and habitat
The "eastern" nominate subspecies of bearded mountaineer is found in the departments of Apurímac and Cuzco of south-central Peru, in the drainages of the Urubamba and upper Apurímac rivers. The "western" subspecies O. n. albolimbata is found in Peru's departments of Huancavelica, Ayacucho, and Apurímac, in the drainages of the Mantaro, Pampas, and Chalhuanca rivers.<p>The species inhabits dry Andean valleys characterized by rocky and scrubby hillsides and open woodland. It occurs in a variety of native plant communities but also is regularly found in tree tobacco (Nicotiana) and Eucalyptus even along roads and in towns. In elevation it ranges from 2,500 to 3,900 m (8,200 to 12,800 ft).

Bronzy Inca
Coeligena coeligena
Large hummingbird known for its remarkably drab plumage: entirely dull brownish with almost no color or iridescence. Throat is slightly paler with scaly appearance. Also note the long straight bill. Sexes alike. Fairly common in Andean cloud forest from Venezuela to Bolivia, from 1,000–2,500 m. Visits feeders.
Cinnamon Ground Dove
Gallicolumba rufigula
A medium-sized ground dove of lowland and foothill forest. Reddish back and wings interspersed with pale blue-gray, diagonal bars. White from throat to belly, edged with black and a messy yellow-orange smudge in the center of the chest. Bobs its head as it walks actively on the ground foraging for seeds and sometimes invertebrates, including worms. Flutters wings when alarmed. Pale, diagonal bars in the wing differentiate it from any other ground-dove. Call, a deep, warbling trill, getting lower and softer at the end.
Puff-throated Babbler
Pellorneum ruficeps
Personable medium-sized babbler, often encountered foraging in noisy, lively flocks on or around the forest floor. Clay-colored with brown-streaked pale underparts. White brow and throat contrast with buffy cheeks and a rusty-orange crown. Occurs from lowlands up into hilly and mountainous forests. Song can be a distinctive series of two to three notes (“two-chee-deer!”), a more extended melodic warble, or a descending chattering trill. Gives rasping, rattling calls, often while flipping leaves on the ground in foraging flocks.
