Cinnamon Screech-Owl
Megascops petersoni
Small screech-owl with a scattered distribution in the Andes. It inhabits cloud forest in southeastern Ecuador and northern Peru, as well as a few locations in Colombia and Venezuela. Most birds have bright cinnamon-buff plumage, but some are brown and tan. Distinguished from the similar Rufescent Screech-Owl by the lack of any white marks on the shoulders, and by voice. Song is a fast, rising and falling series of soft “pu” notes. The speed at which the notes are given is quite variable.

分类信息
The cinnamon screech owl was first described to science in 1986, one of several Megascops owls described at about that time. Its specific epithet honors Roger Tory Peterson, "the father of modern field guides". Its exact relationships to others of its genus are inexact, but it is thought to be most closely relate to the rufescent screech owl (M. ingens) and cloud-forest screech owl (M. marshalli). It is monotypic.

分布与栖息地
According to the International Ornithological Committee (IOC) and the Clements taxonomy, the cinnamon screech owl is only known to occur on the eastern slope of the Andes from southern Ecuador into northern Peru. However, the South American Classification Committee of the American Ornithological Society (AOS/SACC) also places it in Colombia. It may also occur further south in Peru. It inhabits humid montane forest at elevations between 1,650 and 2,225 m (5,413 and 7,300 ft) in Ecuador and 1,700 and 2,450 m (5,580 and 8,040 ft) in Peru.

行为
The cinnamon screech owl is nocturnal, like most others of its genus. Almost nothing is known about its hunting practices or diet, though the latter includes large arthropods and probably small vertebrates.<p>The cinnamon screech owl's breeding season, nest, and eggs have not been described. It is assumed to nest in tree cavities like others of its genus.<p>The cinnamon screech owl's primary (territorial) song is "a flat series of hoots" similar to but faster than that of the rufescent screech owl. Its aggressive song is described as "pu-pu-pu-pu-pu pu pu pu pu pu" that starts fast, abruptly slows, and rises in pitch.

Golden Bush-Robin
Tarsiger chrysaeus
Shining and distinctively yellow robin of the montane forest understory. Male sports a blazing golden brow, yellow underparts, and a black face. Female is less contrastingly patterned, but still noticeably yellow, with browner underparts and a white eyering. Both sexes have a yellow panel on either side of the tail. Song is composed of rolling, buzzing notes; it is not as melodic as those of some other bush-robins.
Taiwan Rosefinch
Carpodacus formosanus
Endemic to Taiwan's mountain forests, this is the only breeding rosefinch on the island. Male deep wine-red with a frosty white brow and dark wings. Female dark brown, finely streaked below. Usually forages low in the forest, in thickets or on the ground. In parks and near villages, often perches up on railings and trail markers.
White-throated Tit
Aegithalos niveogularis
A tiny bird with a small bill, a large head, and a proportionally long tail. Note the white forehead, the white throat, and the partially white collar. Unlike other similar-looking tits, the White-throated Tit has a dark eye. Occurs along forest edges and in alpine scrub, where it forms small groups and participates in mixed-species foraging flocks. Calls include a mix of high-pitched metallic notes, chattering, and dry trills.
