Cloud-forest Screech-Owl
Megascops marshalli
Small screech-owl known from relatively few sites along the east slope of the Andes from central Peru to Bolivia. The bold dark crescents that border its buffy facial disks separate it from Rufescent Screech-Owl and Cinnamon Screech-Owl. Also note the small ear tufts and star-shaped markings on the underparts. Inhabits lush, ephiphyte-laden cloud forest. Typical song is rapid series of soft whistles (“pu-pu-pu-pu-pu…”), slightly faster than Cinnamon Screech-Owl and lower-pitched than Rufescent Screech-Owl.
识别特征
The cloud-forest screech owl is 20 to 23 cm (7.9 to 9.1 in) long; a male and a female weighed 105 g (3.7 oz) and 115 g (4.1 oz) respectively. It is among the smallest screech owls. It has a rufous facial disc with black edges on the sides, white brows over dark brown eyes, and short "ear" tufts. Its crown and upperparts are a rich reddish brown with blackish mottling and a buffy nuchal "collar". The folded wing shows a line of white spots and the tail is barred. Its breast is rufous with dark streaks and thin vermiculations. Its belly is off-white with dark streaks and thin barring.
分类信息
The cloud-forest screech owl is monotypic. Its nearest relatives are the cinnamon screech owl (Megascops petersoni) and Yungas screech owl (M. hoyi) but their exact relationship has not been settled. The species' specific epithet commemorates Joe T. Marshall, "the modern-day student of nightbirds".

分布与栖息地
The cloud-forest screech owl was originally thought to be confined to south and central Peru, in the Departments of Pasco, Cuzco, and Puno. Since 2005 it has been recorded in northern Bolivia as well. It inhabits cloud forest, a humid, mossy landscape with epiphytes, ferns, and a dense understory. In elevation it ranges at least from 1,900 to 2,600 m (6,200 to 8,500 ft) and possibly higher.

行为
The cloud-forest screech owl forages in the canopy; it is believed to be mostly insectivorous.<p>Very little is known about the cloud-forest screech-owls breeding phenology. It appears to breed between late June and August and is assumed to nest in tree cavities like others of its genus.<p>The cloud-forest screech owl's song is "a continuous series of monotonic hoots" whose intensity increases and then ends abruptly. It also occasionally utters a "trill-like short song".

Chestnut-headed Chachalaca
Ortalis ruficeps
Slender, long-tailed, chickenlike bird that is often seen in small groups. Grayish-brown overall with a warmer chestnut head. At close range note the bare red throat patch and pinkish legs. Found in forest, second-growth woodlands, and river edges. Limited range in central Brazil, south of the Amazon river.. Somewhat similar to Spix’s and Marail Guans, but Chestnut-headed Chachalaca is much smaller and is unlikely to be in canopy of tall forest. Usually quiet, but groups call loudly to each other early in the morning; unmistakable call can be heard for more than a kilometer. Once considered conspecific with Variable Chachalaca, but Chestnut-headed is smaller and has a slower song.
Great Tit
Parus major
Conspicuous inhabitant of woods, forests, parks, gardens, and hedges in farmland. Often visits bird feeders and uses nest boxes. Plumage is distinctive, with white cheeks surrounded by a black cap and bib. Male has a broader black stripe down belly than the female, and the juvenile (seen in summer–early autumn) has yellowish wash to face and drabber plumage overall. Underparts are bright yellow throughout much of range, but “Turkestan Tit” of Central Asia has a white belly. Appreciably larger and more boldly patterned than Eurasian Blue Tit, which often occurs alongside it. Listen for its distinctive high-pitched up-and-down song: “tsee-dee-tsee-dee-tsee-dee” and chattering scolds.
Chestnut-bellied Imperial-Pigeon
Ducula brenchleyi
A large dark pigeon with a deep chestnut belly and undertail. Entirely dark above with a contrasting paler head. Chestnut underwing separates this species from any other similar pigeon. Rare. Prefers very mature undisturbed hill forest. Most common call is a deep, drawn-out “whu-ooooow.”
