Tibetan Eared-Pheasant
Crossoptilon harmani
Distinctive slate-gray pheasant with a bright red face, scraggly fan-shaped tail, and bizarre white whiskers (the namesake “ears”). Also note black cap, pale gray rump, and whitish belly. Restricted to the southeastern Tibetan Plateau, where it inhabits areas with dense scrubby or brushy cover. Typically at 3000-5000 meters, though it is known to descend in the winter. Regularly found around monasteries which put food out for wildlife. Forages on the ground in small to medium-sized flocks. Can be vocal, giving high-pitched grunts and a rising squeal: “gu-tse-WEEW!"
识别特征
The Tibetan eared pheasant shares many characteristics, such as the short ears and the droopy tail, with the white eared pheasant (C. crossoptilon), as well as having similar calls and hybridising with it in the Salween Valley, so the two may be conspecific. The Tibetan eared pheasant grows to a length between 75 and 85 cm (30 and 33 in), with females being slightly smaller than males. The sexes are similar. The beak is reddish-brown, the irises yellowish-orange, and the bare facial skin is red, as are the legs. The head is topped with a crown of black, dense, short feathers, on either side of which are short, nonprojecting ear tufts. The rest of the head and nape and a thin collar are white. The rest of the body, wings, and tail are bluish-grey, the mantle, neck and breast being of a darker shade, whereas the lower back, rump, upper tail coverts, and belly are paler whitish-grey. The wings are blackish-brown and the tail bluish-black.

分布与栖息地
Their range is restricted to Tibet, northern India, and northern Bhutan. Their typical habitat is dense scrubby areas in river valleys, grassy hillsides, and the verges of both coniferous and deciduous woodlands. Although sometimes found at elevations as low as 2,400 m (7,900 ft), they usually occur between about 3,000 and 5,000 m (9,800 and 16,400 ft).

行为
These pheasants usually form groups of up to 10 individuals. They feed on the ground, foraging through the plant debris and grasses near woodland edges and among the rhododendron and juniper scrub. In areas where they are hunted, they may be elusive, retreating into the undergrowth or flying off downhill when scared, but where unmolested, can be quite bold. The birds are believed to be monogamous, with breeding taking place between May and July. One nest was discovered under a fallen tree trunk; it was made from bark and pulp with a mossy lining. The female seems to be solely responsible for incubating the eggs, but both sexes have been observed feeding the chicks.

Yellow-necked Greenbul
Chlorocichla falkensteini
A medium-sized greenbul of thickets and tangles that prefers edge and semi-disturbed habitats. Most often seen in pairs or small family groups, but it will occasionally join other species in flocks. Gray below except for a bright yellow throat, and uniformly yellow-green above with reddish eyes. Most likely to be confused with the similarly named Yellow-throated Greenbul, which usually has a paler whitish throat in areas where the two species overlap. Yellow-necked Greenbuls can be distinguished by their uniformly gray underparts, brighter olive-green upperparts, dark red eyes, and consistently bright yellow throats. Voice is a variable subdued chatter, “kur-ku-kurkwu.”
Patagonian Tyrant
Colorhamphus parvirostris
Rather plain but subtly attractive little flycatcher best known in migration and winter, when it occurs widely in gardens, parks, and open woodlands, often with fruiting shrubs. In summer, inhabits temperate native rainforest where it often stays rather high in the trees and is easily overlooked. Found as singles and pairs in summer, but sometimes small flocks in winter. No similar species in range: note the rounded head with dark cheek patch and rusty wingbars.
Marbled Duck
Marmaronetta angustirostris
Small, subtly beautiful, gray-brown duck with a black eye-mask, long neck and wings, and dark bill. Vaguely resembles a female pintail. Both sexes are similar but males sport a more prominent shaggy crest. In flight looks pallid, with whitish underwings, pale secondaries, and dark wingtips. Mostly silent. Typically found in shallow, freshwater or brackish wetlands with abundant emergent vegetation.
