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.

Blue-crowned Parakeet
Thectocercus acuticaudatus
Bright green bird with blue crown and face, distinct white eyering and long, pointed tail. Native to lowland dry forest and scrub in South America; introduced to urban areas in south Florida, California, and Honolulu, Hawaii. Often seen in small flocks; can travel large distances between roosts and feeding areas. Listen for high-pitched grating calls.
Henst's Goshawk
Astur henstii
A big, powerful goshawk. Adults are gray on the back with fine gray barring below; females much larger. Immatures have a brown back and thick streaks below. Endemic to Madagascar, where it is a scarce resident of all types of primary forest. Rarely sits in the open, and only occasionally soars. Territorial call is a loud repeated “khew” which is often given in flight. Males can be very hard to separate from similarly-sized female Madagascar Sparrowhawk. On Henst’s, look for fine bars on the undertail, a completely barred throat, and a central toe of normal length. Immatures may only be separable based on toe length. Also very similar to the rare Madagascar Serpent-Eagle. Subtle differences include slightly smaller size, evenly-spaced barring on the chest, thicker black bands on the tail, and an unbarred back.
Dambo Cisticola
Cisticola dambo
Small cisticola that is pale and buffy below, and dark on the back. The crown, back of the neck, and back are heavily streaked. Note specific habitat preferences, which can help with identification: found in seepage zones of seasonally wet grasslands, alongside but in wetter situations than Wing-snapping Cisticolas, but avoiding the seasonally flooded habitat of Pale-crowned Cisticola. Very similar to Wing-snapping and Pale-crowned Cisticolas, but longer-tailed than both, and further distinguished from Pale-crowned in breeding plumage by the streaked crown. Also similar to Zitting and Desert Cisticolas, but has a different voice, and is darker on the back. Song consists of nasal notes, given from a low perch (termite mound or grass stem) or occasional brief display flight at grass top height. In contrast to other small cisticolas, it does not have a true aerial display flight.
