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".

Delta Amacuro Softtail
Thripophaga amacurensis
Distinctive streaky brown bird of riverine habitats of the Orinoco Delta. Most of body brown with buffy streaks (tear-shaped on underparts). Rich chestnut on chin, wings, rump, and tail. Sexes similar. Locally common and often in pairs, found from understory to canopy in riverine forest where often climbs trunks like a woodcreeper. Voice is an explosive group of short notes, mostly in duet. Similar to Orinoco Softtail (no range overlap), which is less streaked and has a buff eyebrow; Rusty-backed Spinetail is unstreaked. Endemic to the Orinoco River of northeastern Venezuela.
White-winged Collared-Dove
Streptopelia reichenowi
A distinctive dove with a restricted range. The white wing patches are usually visible when perched, and become very conspicuous in flight. A white eye-ring is conspicuous at close range. Found locally in riverside scrub, thickets, and adjacent habitats. Similar overall to Ring-necked Dove, but separated by the white eye-ring, gray breast, and white wing patches. The song is a fast-paced, quickly repeated rolling series of cooing notes with a somewhat rough, churring quality.
Siberian Crane
Leucogeranus leucogeranus
Rare and declining, but still fairly abundant at its main wintering grounds at Poyang Lake, in China’s Jiangxi Province. Adult is unmistakable with all-white plumage, save for a crimson face and black wingtips. Juveniles are whitish, with a light brown head, neck, back, and wings. Typically found around lake edges and fields, where it forages in small to medium-sized groups, primarily for plant matter and invertebrates.
