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.

Abyssinian Scimitarbill
Rhinopomastus minor
This all-black bird has a curved orange bill and a fairly long tail. Northern birds have white bars across the wings, which are conspicuous in flight, while southern birds have entirely black wings. Found in dry savanna and thornscrub. Separated from other scimitarbills by its orange bill. Similar to some woodhoopoes, but separated by its smaller size, shorter all-black tail, and black legs. Vocalizations include a series of wavering, rising notes and an agitated-sounding series of “dok” notes.
Yellowish Pipit
Anthus chii
Rather dull buffy ground-dwelling bird with a large but disjunct range from Panama to Argentina. Streaky brown above and paler below with a streaked breast and plain belly. Note long pinkish legs and white outer tail feathers. Found in any flat open habitat including savannah, agricultural areas, and desert. Most often seen on the ground, occasionally perched up on a small shrub or fence. The only pipit in most of its range. Listen for the distinctive song, a few tick notes followed by a long descending buzzy “tzeeeeeeew,” often given in flight.

A tiny gray finch with a red tail and rump and a purplish bill. Male is bright silvery-gray all over with a pale throat and chest. Female is similar, but has darker underparts. Sometimes joins flocks with other small finches. Inhabits thickets in open areas such as hillsides and field edges. Call is a high, thin “see”, often given in series. Native to western Africa; introduced to Hawaii island, where it inhabits brushy and grassy areas.
